[OpenLayers-Users] GetFeatureInfo requests never get answers

[Marc Desharnais]

Hi Christopher,

Like you said, it turned out that the problem was a security issue.
To those who don't know (like me), you can't access a host with your 
browser and make query on another. The point I was missing was that the 
same machine with 2 different ports are considered to be 2 different 
hosts. It's a simple explanation when you realize that.

I learned too why the security exception in Firefox while I attempted to 
make request (via Firebug) didn't show like I would have expect.
That's a thing that really bothered me at the first place because I 
would have expected an clear error from the browser.
I have read that this kind of exception are treated silently in the 
browser so it's normal I've seen nothing while I was debugging.

Now everything is working well!

Thank you for your supportt! :)

Marc
