collective.embeddedpage's Issues

Requests to URLs that do not respond run on forever

When calling an URL via an embeddedPage that does accept a connection but never sends a reply, this addon will not run into a timeout and will wait forever for a reply. On high traffic sites this can lead to resource exhaustion on the Plone servers as there is a limit to the open connections an instance can have open.

Steps to reproduce:

• Create a web application that accepts a connection but does not reply (Simplest solution is to create e.g. a php script with sleep(999) and put it on a server with PHP support
• Enter the URL of the above mentioned script into an embeddedPage (You might need to remove the sleep() for this step as the document will only be saved once the entered URL has been reached)
• Call the embeddedPage in Plone

What happens:

• The page loads forever in the browser without showing a result (Depending on the Plone setup there might be a timeout e.g. in a reverse proxy in front of the Plone instance.)
• Even if the loading process in the browser is aborted the call from the Plone instance to the entered URL will still be kept open until either a response is received or the instance is restarted.

What should happen

The request to the external URL should time out after a certain time and an error message should be shown.

error at creating embedded page

Whenever I try to add a new embedded page I get following error at the end:

Further information: I'm using Plone 5.2.4, latest collective.embeddedpage (=2.2.1), the html file in the url is very basic...
Thanks!

Title is showen doubled when add embeddedpage

Please take out the 'Title' in schema, because there is already a 'plone.namefromtitle' behavior

Volto support (REST API, Plone 5.2)

• Write a serializer that does a request to the site under the "URL" attribute.
• Plone RESTAPI returns a "normal" result in the text field:

text: {
  "data": "<p>HTML CODE FROM THE EMBEDDED PAGE</p>",
  "content-type": "text/html",
  "encoding": "utf-8"
}

Support pip-based installations

Multilingual behavior for EmbeddedPage

Would you please add behavior 'plone.app.multilingual.dx.interfaces.IDexterityTranslatable' to Embeddedpage?
Thank you!
