Javascript, Chrome Extension development, XMLHttpRequest Access-Control-Allow-Origin problem

Question

Am having a slightly confusing problem with this extension (although it might just be my inexperience) in my manifest file I have:

"permissions": [ "http://mafre.com/","http://eee.se/","http://ilaafire.net/","notifications","tabs"

And i am using this code to send an XML request:

var http = false; http = new XMLHttpRequest(); function replace() { http.open("GET", "http://www.mafre.com/proj/test.php"+getquerystring(), true); http.onreadystatechange=function() { if(http.readyState < 4) {show_wait_gif();} else if(http.readyState == 4) { updatepage( http.responseText); } } http.send(null); }

which my script on the other end is getting the data... but when I need to get the response Chrome is throwing this error:

XMLHttpRequest cannot load http://www.mafre.com/proj/[email protected]. Origin chrome-extension://kjggpdimdloblnddfbnodggchjpalihb is not allowed by Access-Control-Allow-Origin.

Why is that? I have already given it permission to interact with the domain so why cannot I get the response even though it is sending the query?

The response that I should get back into my page is something like "email accepted, thanks!1"

Thanks!

I believe you should wildcard permission URLs, also www. is a different domain:

"http://mafre.com/*", "http://www.mafre.com/*", "http://eee.se/*", "http://www.eee.se/*", "http://ilaafire.net/*", "http://www.ilaafire.net/*", "notifications", "tabs"

Currently you only have access to exactly http://mafre.com/.

@Ryan: It does for me. Did you reload the extension?

@Ryan: I uploaded the most trivial version and it works: 2shared.com/file/850FaUZF/origin.html.

ARRRGH! My stupid fault, i had two manifest files open and was editing the wrong one (serious DUH! moment). Your solution works perfectly and sorry for the above. Wish i could vote up your help x1000, and another x10000 for my stupidity. Thanks again!
