[news.eclipse.tools.pdt] Re: PDT / Xdebug / Multiple sub domains

[Shawn Clark <shawn_d_clark@xxxxxxxxxxx>]

Ah... that is sort of what I was thinking but it wasn't working and now 
I think I understand exactly what the problem is and it isn't so much a 
problem with PDT as it is with Xdebug.

When Eclipse loads the URL in the server configuration for the debug 
session it passes along the information which Xdebug then puts into a 
session cookie for the browser. The thing I am guessing is happening is 
that the cookie is only for the current domain and not any sub-domain of 
that domain. So when I am going to a sub-domain the cookie isn't being 
passed to Xdebug and as such Xdebug isn't relaying the absolute path 
information to the IDE.

I am going to test now and will see if that is the case. I will just 
watch where Xdebug tells the browser to assign the cookie. I am guessing 
it is just for the main domain that is for the URL that is set in Eclipse.
