XMLHttpRequest for chrome-extension protocol

[Marek Sebera]

Hi,
I'm using background page and I need to inject some code into current
tab contents.

so I do following:

-> define browser_action
-> define listener like this
chrome.browserAction.onClicked.addListener
-> calling script loaded by content_scripts via
chrome.tabs.executeScript

And from page content I need to load html resource from within
extensions folder.

but using this XMLHttpRequest gives me error Cross origin requests are
only supported for HTTP

handled by XMLHttpRequest by error NETWORK_ERR: XMLHttpRequest
Exception 101

Note: address is like chrome-extension://someextensionid/file.html

So how am I supposed to solve it? How can I load local extension
resources from files?

Hey Marek,

Take a look at http://code.google.com/chrome/extensions/xhr.html. Basically you need host permissions.

Really ?

I'm pretty sure this sentence says the opposite:
"Without requesting additional privileges, the extension can use
XMLHttpRequest to get resources within its installation."

Apologies, I completely misread your question. Please defer to Mihai's answer :)

It works like that for my extension. I can access chrome-extension://
my-extension-id/* files using XMLHttpRequest without asking for any
explicit permissions.
And in the latest canary/development versions I also see with the
webRequest API all network transactions involving chrome-extension://
my-extension-id/* URLs
