Magento CE 1.9.0.1, FPC::Lesti is caching Community Poll I guess because when I vote the side block remains unchanged, ready for another vote, but not showing any results.

I need a solution to skip caching for Community Poll side block. I can keep Polls hide for a while, but not too long. Thank you.

Hi!

This is a suggestion for add an option in the admin panel for flush the cache regarding about concret url.

This method is used in CDN like cloudflare, and is very good for only delete the cache related for example with one product or one cms, and no need to delete the previous cached products/cms, etc.

thanks.

We are showing delivery time on product pages based on inventory level. This is ofcourse cached. After a product is saved in backend the cache gets refreshed correctly so the data in frontend is correct.

But if the product is purchased the cache is not refreshed. Is there a way to force a refresh on productpages after they have been ordered? There is an method for clearing the cache allready.

catalogProductSaveAfter, this refreshes cache, it is fired trough this event: cataloginventory_stock_item_save_after

Related to #11.
One way to go around this would be the possibility to ignore block types. The block name ignore feature doesn't help since they can be user generated on my website.

Hello,
i am using better_configurable_products swatches on my product_list added to product_list in my local.xml. The block (product.info.swatches) is working completely correct when used without lesti_fpc
$this->getLayout()->getBlock('product.info.swatches')->setProduct($product)->toHtml() is called in the template and it works like a charm (setProduct() sets the cache-key according to the acutal product).

The Problem now is, that with lesti_fpc, the setProduct() seems to be ommited, even if i enter the blockname to the dynamic-block-list in the backend.
Do i get it right, that the cache is looking for the block by name and delivering it before even setting the product and my idea to have it as dynamic block is not that clever because even dynamic blocks are only rendered once per page load?

I'm getting a lot of these warnings in the system.log:

2014-05-26T08:29:13+00:00 ERR (3): User Notice: 'hashed_directory_umask' is deprecated -> please use 'hashed_directory_perm' instead in /lib/Zend/Cache/Backend/File.php on line 144

Hi Gordon,
Really like you work and wanted to know if I need to "enable" something in the backend in order to get the layered navigation working?

Issue is that the actual filtering is not functioning.

Tested on Magento 1.7.0.2. on the default theme.

Thanks.

It would be nice, if the extension also minified the html code. It is good for page speed and little bit for SEO

Enable Memcache for FPC in fpc.xml.

Disabling Memcache with FPC enabled causes the frontend to crash.

Many Thanks,
Shaun

Hi Gordon,
I have installed your fpc with Ajax extension.
But not the messages block is showing below the home page content instead of at the top after_body_start position.

Any ides why? Or how to solve? Thanks

I have a few blocks which change when the user is logged in, alas FPC doesn't recognize that event and outputs the cache as generated at 1st access.

Hi Gordon,

Have a 1.7.0.2 site running the latest Lesti_Fpc backed by redis/cm_cache_backend_redis. It's raising the error

2013-08-27T20:55:13+00:00 CRIT (2): Not valid template file:frontend/base/default/template/fpc/catalog/product/view/ajax.phtml

in var/log/system.log.

File is unchanged by us. Should I be worried?

Cheers,

Steve

It would be great if lesti_fpc had support for glob or regex in uri params. I'm using a layered navigation module which uses uri params like 'filter_size' and 'filter_color'. If you don't want to update the cache configuration when adding a new attribute or just have dozens of them, adding one pattern to match them all would be great.

Thanks for share your work!

I am showing the real stock in numbers in the frontpage.

I have a custom develpment extension that show the stock of all the combinations in a configurable product. In concret are t-shirts with differents color/sizes, and when you click in any color, appear the disponibility quanty of each size of this color.

I was tried to modify the stock in one simple product assigned to a configurable product, but still showing the old stock because is cached too.

Mabye you can add an option for auto-refresh the information in the cached files regarding about the stocks when was changed in any product.

thanks!

I have two magento shops (v. 1.6, both are configured almost exactly the same way and use the same plugins). In your extension has a big impact and I get server response times of about 500ms.. On the other shop, I can't notice any difference. The page load time varies between 2 and 3 seconds.

I have enabled the FPC cache under System | Cache management. Other than that, I haven't changed any configuration. I also looked into the var/cache folder and fpc--xxx folders get created. Do you have any idea what the reason for this behavior might be?

It looks like product-category-title is caching one instance .

instead of multiple per category

We have 3 categories that contain several overlapping products. Depending on via which category you get to this shirt the title above the t-shirt differs: http://shirtsofcotton.com/medium-v-shirt.html

Me Again, Gordon,

Line 74 in Observer.php

$blockName = $blockName == 'global_messages' ? 'messages' : $blockName;

Is forcing the placeholder for global_messages to be "messages". So, when we subscribe to the newsletter, it's coming through as a global_message and there's no placeholder for it and so it does not get replaced. By removing this line, the global_messages placeholder is maintained in the FPC and so the replacement works correctly and the newsletter subscribe message is shown correctly.

My question is, what was the purpose of forcing global_messages to be messages?

I am currently experiencing a problem where Lesti Fpc is falling back to file eventhough the memcached server is up & running. I have enabled debug but do not see any results from this anywhere.

Hi Gordon,

I'm seeing issues with the currency switcher being applied. The "cart" is updated because that's a dynamic block. If I apply it as a "dynamic block" (it should really only affect the switcher anyway), the currency switcher disappears but the prices are not switched.

I think we'd need to catch a currency switcher event and clear the cache. Hopefully, I can spend more time looking at it tomorrow.

On our development server when FPC is enabled some link urls have ?___SID=U randomly added to the end.

To create the issue we navigate around the site and within a short time the problem will occur. It seems to randomly effect urls that are automatically generated i.e toplinks like account login and related product links. Refreshing the page by pressing F5 will fix the URLs

Disabling Blocks HTML output in Cache Storage Management fixes the problem, but obviously we would rather not leave this disabled permanently.

(not a real issue, nut maybe an idea for further improvement)

Hi, today I noticed that customer ratings on product pages (the stars) are cached and not updated through dynamic or per customer basis.

Is there a way to flush the cache one ratings get approved in the backend (resulting in a page update)? Or make it lazy per default?

Hello Gordon,
I've 1 error and 1 warning in the log files.

Hi,

I just installed your extension, and I have to say it's really great. I was previously using Varnish + a custom ESI mechanism but it was too complicated to adapt after the upgrade to community 1.8 because of the introduction of form keys on the frontend.

I'd like to know how I can debug my custom template to find why the URLs like

/catalog/product_compare/add/product/26456/uenc/aHR0cDovL2Rldi5sZXBhcGUuY29tL3NhbG9tb24tcy1sYWIteHQtNi1zb2Z0Z3JvdW5k/

don't work when I'm in a different session from the one who cached the page first.

Thanks!

Hi, all, I m having issue with mini cart on right top of my template which does not stay dynamic, i.e, FPC caches it. When product is added, it changes, but when I go back to homepage, homepage does not reflect the items, this is happening with all the pages, i.e, minicart status of that particular page does not carry forward to next page, be it homepage or any other page. Please help how to solve this.

Hi guys,

Came across this issue while working on a client's site.

Bulk updating products through the admin panel doesn't currently trigger a cache refresh. ie: bulk updating products to become 'in stock' will result in FPC still showing out of stock on the product & category pages.

Mass action updates don't fire the standard catalog_product_save_after event, however we do have a few events that we could use...

Looking at the core events, i can see catalog_product_attribute_update_before is called before the update is made, this has the product ids to be updated

Unfortunately, there isn't an 'after' event that provides the product ids, however we should be able to refer to the event end_process_event_catalog_product_mass_action and process the previous event details.

ref: http://magento.stackexchange.com/questions/9067/catalog-product-save-after-event-for-massaction

I would like to suggest an implementation of a config to specify different cache TTL for specific cachable actions.
For example the cms_index_index (homepage) could have a shorter TTL than the catalog_product_view.
Thanks

With Lesti_FPC and persistent cart enabled, when you try to close session is not working very well and stay showing the prices of the customer group of the previously logged user instead of the "not loggued in" user.

With persistent cart, normally appear a top message that say "¿not be "name"? and if you click appear the normal prices, but with fpc enabled don't appear. Sometimes appear, but when you click it, dissapear this link but still loggued.

The option for exit the session don't appear more.

Disabling fpc or disabling persitent cart work all ok. Actually we have disabled the persistent cart and works perfect.

Thanks for the great product

We have to set fpc.xml to our hosting settings, but we cannot edit/write to the default installed files via modman clone

Is this correct?

Hi Gordon

Can you take a look on http://penelopeestilosa.com ?

I use Apptha´s Social login and FPC 1.4 (for about 1 year) and when you login the top links aren´t refreshing. For example try to logout or my account and it will still shows social login lightbox.

I use top.links as dynamic block in FPC admin options ? Is it correct ? How to fix this issue ? Currently I have to disable FPC to work fine.

Thank you and congratulations for FPC!!!

Seems LestiFPC doesn't clean up the cache storage.
After LestiFPC killed my 2GB instance of Redis i decided to try a different storage (to file) and... to my surprise the cache directory keeps growing.
Once it reached 28GBs and i'm forced deleting the cache folder with a cron job.
I guess it's a bug.

Hi Gordon,

I've tested many FPC's but your goals fit with what I'm looking for in an FPC - ie: little or no Ajax and no Varnish requirement

Compared Products block only working when user is logged in. When logged out, "No Products to Compare" - messages for this block are working and if you add something and then either turn the cache off or login, it also shows.

Not sure if related to #45 but...

Another magento plugin, Catalin SEO, does some AJAX requests, which I are being cached by your plugin.

Problem is, when they are loaded from your cache, you are sending it as text/plain which is crashing the js that receives it.

For the cache misses, it works, and is sent as application/json correctly.

Wondering how I could either blacklist Catalin SEO ajax thing from being cached, or whether your plugin could be extended to remember the mimetype when re-sending.

Thanks

Hey Gordon,

Sorry for asking but what is the exact reason for using serialize and unserialize
here and here ?

You only have two entries in that array which can be refactored to e.g.

$fpc->save(time().$body, $key, $this->_cache_tags);

and

$object = $fpc->load($key)
$time = (int)substr($object,0,10);
$body = substr($object,10);

There are many results on google explaining the poor performance of serialize ...

Or if you would still like to use serialize() or json_encode then at least create a fallback to https://github.com/igbinary/igbinary which is overall faster than those previously mentioned methods ...

If you think this issue sucks ... just close it otherwise I can send you a PR 8-)

Cyrill

Currently the lifetime is always "null", which translates to "infinite lifetime". See my commit: novalis111@74cb8c2

I couldn't create a pull request because of other code changes, sorry.

With the latest version of the module i experience an issue with the product images when viewing an category.

After flushing the cache all images dissapwar on the website. Flushing/refreshing it again, restarting nginx, php-fpm, redis won't help to solve the issue. Only way to get the images back is disable the FPC cache, flush everything and then turn the FPC back on however the problem will appear next time the cache has been flushed.

Anyone else having this issue or am i the only one?

When running dedicated mobile themes (tested with aw_mobile and Magento 1.7 native), whichever page is loaded first; Desktop version or Mobile version is then displayed by the FPC to end users for that page.

I've managed a rudimentary workaround on the awmobile version by calling one of their functions

Mage::Helper('awmobile')->getTargetPlatform() and only load / apply FPC if it is the desktop version.

Haven't yet had time to take a look at the Magento 1.7.2 theme yet.

Again thanks for this plugin. I notice an ssue this week....

When users log into Magento the login button still shows "login" for cached pages. It shows logout out only if cache is purged.

Is there a way to fix this?

I think that is good to have integrade in Lesti_Fpc an auto-crawler that continuosly is caching the website, something like if a bot load the web and is the cache was refreshed for the crawled products automatically.

Obviously this crawler need to have something for avoid the server is full all time. Something similar to this:
http://ecommerce.brimllc.com/cache-warmer-for-magento.html
or this:
http://www.extendware.com/full-page-cache-crawler-magento-extension.html
thanks!

Hi Gordon,

I noticed an issue with your implementation. We have multiple tax rates, so the catalog prices change depending of the shipping address of the currently logged customer.

When this happens, if a page is not already cached, it will be stored (obviously) but this lead to pages with different prices tax rates.

Any pointers on how I could implement a check against the currently logged customer, or add a tax rate parameter in the URL hash?

The problem goes to Catalog Price Rules. Long story short, when FPC is enables everything works perfectly, all pages are cached and no problem, but when Catalog Price Rules is active and automatically change the price (crontab) the old price still cached in catalog. End when the client is looking at the catalog – they see cached prices (old ones) instead of real ones. But when they add products to cart the real price reveal itself (which is different). Is there is a way to flush a cache when Catalog Price Rules are in action?

Hi
I have installed the extension, when I enabled the extension then frontend layered filter is not working,
after disable the extension frontend layered filter is working,
Can you please let me know the solution of this issue?

Thanks
