Hia...

Not an issue as such, I was just wondering if you could chain this proxy with 
Privoxy to make use of both applications?  I couldn't see how to do it myself 
and haven't found any explanations on web searches so this is more of a 
question than a problem.

1. Find an image
2. Download it
3. Try to open to receive error

What is the expected output? What do you see instead?
I expect an image.
I see a corrupt file.

Latest version on Windows 7

Please provide any additional information below.

i want to change proxy to compress.googlezip.net:80

as it is not encrypted so i will get at least get significant boost

because in my network https works very slow

can  u atleast give me method to change proxy please

An Enhancement:

It would be awesome if you could alter the extension icon when you are on a 
bypassed page/ip/domain etc.

Essentially one state when you should expect it to be 'compressing' and another 
when not. Similar to how you can turn it on/off.

Thanks!

Add link to chrome://net-internals/#bandwidth to options page. Putting it there 
should increace usability, it's a way to check whether the extension is working 
correctly.

What steps will reproduce the problem?
1. Slimjet version is 3.0.3

What is the expected output? What do you see instead?

All sites is blank when data compression proxy is on

What version of the product are you using? On what operating system?
Win 7x86, 2048 RAM

What steps will reproduce the problem?
1. Install one other popular adblock extension (adblock plus/adguard adblocker)
2. Go to the site with ads that both extension should disable (most popular 
sites that uses Google AD network)
3. Chrome will show "Warning:
This extension failed to modify the request header "Chrome-Proxy" of a network 
request because the modification conflicted with another extension (Data 
Compression Proxy)."
Also Data compression's proxy icon will change to yellow "Temporary disable" 
after page reloading

What is the expected output? What do you see instead?


I'm using Chrome Version 40.0.2214.115 m (64-bit) on Windows 7 (64-bit)


Maybe let other extensions cut ads and completely remove this functionality 
from "Data Compression Proxy"

Google Chrome Version 41.0.2272.101 m  - on Windows 8.1
Added: Data Compression Proxy -from niu tech   from chrome webstore. to the 
chrome browser.

I realized blocking any of the below links, couldn't restrict the DCP.

check.googlezip.net/connect
proxy.googlezip.net:443
compress.googlezip.net:80

What is the expected output?
The proxy should work.


What do you see instead?
Seems that Google did yet another code change that breaks the extension. The 
initial HTML source code seems to load properly, but the stylesheets and 
Javascripts don't load, and when you reload the page, you'll get the error code 
ERR_NO_SUPPORTED_PROXIES.


What version of the product are you using? On what operating system?

Can You add function proxy for list?

Example:
Turn on the mode proxy from list.
Fill in the required list of sites.
Proxy is used only sites from the list.
In other cases, a proxy is not use.

Sorry for bad my English. I use google translate.

What steps will reproduce the problem?
1. Using Google Chrome Version 39.0.2171.62 beta-m (64-bit)
2. Enable Data Compression Proxy plugin
3. Open chrome://net-internals/#bandwidth in new tab
4. Begin browsing in standard mode

What is the expected output? What do you see instead?

I expect to see the bandwidth monitor update to show traffic savings. Instead, 
with the exception of the "Original" and "Received" fields updating, the 
"Savings (KB)" and the "Savings (%)" fields remain at 0

Compression does occur but the statistics do not display this

What version of the product are you using? On what operating system?

Google Chrome Version 39.0.2171.62 beta-m (64-bit)
Windows 7 Professional 64-bit (SP1)


Please provide any additional information below.

If I open an incognito tab with compression enabled and open the bandwidth 
monitor in another incognito tab, the statistics update as expected

The DCP relies on a correct Proxy-Authorization header based on a timestamp, 
which is hard-coded for now. We should find out the SPDY_PROXY_AUTH_VALUE and 
dynamically generate the header value, using functions:

ps = function(timestamp) { return timestamp + '-' + rand() + '-' + rand() + '-' 
+ rand() }
sid = function(timestamp) { return md5(timestamp + SPDY_PROXY_AUTH_VALUE + 
timestamp) }
proxyauthvalue = 'SpdyProxy ps="' + ps + '", sid="' + sid + '"'

2. Load random websites (HTTP, not HTTPS)

restarted computer, and reinstalled plugin.

Chrome Stable 34.0.1847.116

who has a different ISP with no luck

i can not open some web pages via datacompressionproxy.
for exemple habrahabr.ru

1.Turn it on
2.Try and browse

data compression proxy on my android using same wifi)

Thanks for this extension.
It would be more useful if it had 
a) detailed instructions for the adblock list not just data format.
b) ability to use a copied version of the easy list file that is maintained for 
comprehensive adblocking. do a search for 'easylist' to find.

Several users with the same problem (some of them wrote on the Chrome Extension

Not a problem.
I was wondering if this can be enabled for https sites or does the encryption 
make this impossible?

I only have 2 gig of data per moth and want t use Google Drive etc.
I could then manually disable this for online banking etc.

Dear Admin,

When I use this extension, sometimes it shows warning message saying that 
cannot change "chrome proxy" and sometimes web pages are not loading 
properly(crashed images and displaced content). I am facing this problem from 
last few days. Disabling this extension solves the problem.

I am using chrome Version 39.0.2171.13 beta-m.

Kindly resolve this issue.

Thanks,
Sudheer

Mozilla has recently released an extension that is (almost) the same as the 
Data Compression Proxy available in Google Chrome for Android. 

The extension has an adblocker and other nice settings. (Convert GIF to video, 
and optimized for latency instead of bandwidth). 

1. Disabled aaaall another proxy stuff
2. Open rndm webpage in a tab and chrome://net-internals/#bandwidth in other. 
Refresh first one for times.
3. Wrong!

Expected compression. Nothing changes in last 2 lines of stats.

Chrome 34.0.1847.76 beta-m
Windows 8.1 x64 build 6.3.9600
Java 7 upd 51 x86

What am I doing wrong? Maybe it wouldn't work in Win 8 at all?
Give me assistanse please.

It would be quite useful for anyone using this extension only for certain sites.
Personally I'm switching it on only to visit some sites blocked by government.

Hi, I'm currently abroad and tried using the proxy extension without success. 
My goal is to be able to use Netflix and Pandora. The extension says that it's 
working (green), but I'm not able to use either of the sites. I'm probably 
overlooking something obvious, but it's my first time using a proxy. 
Help?

Thanks!

My internet connection is slow , sometimes page loading takes longer time,in 
that case you open require page in new tab,and close current tab,so connection 
of close tab must be terminated, but instead its keep running.

sorry for the language ,but can u understand the problem?

datacompressionproxy does not uses system proxy specified in Internet Options. 

In case the original method of connection was through a proxy server, 
datacompressionproxy would not use that and try a direct connection instead.

What version of the product are you using? On what operating system?
Chrome 36.0.1985.143 m on Windows 7 x86

Currently a proxy bypass list is defined in the code.  It would be a useful 
feature to allow the user to add to the bypass list so they can bypass any 
websites that may not be working with data compression.

Add option to turn proxy off for compressed images, video files/streams and 
maybe other famous non-compressible data.
