Hello,

whenever I profile code with debug session enabled profiler data is missing for every second request I make.
SQL profiling works, but nothing else.
I did some short research and it seems like the DBGSESSID value is not handled properly.

1st request (profiling ok):

Code:

GET /test/ HTTP/1.1
Host: localhost
Connection: keep-alive
Cache-Control: max-age=0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8

As you can see the D parameter is changed from 17 to 145 which then results in missing profiler data for the next request.
The other way, when D=145 is sent, it is changed to 17...

I'm running dbg-5.0.8 for php 5.4 windows and php 5.1 linux.

How can I solve that?

First of all, dbg-5.0.8 was released in Feb 2013 and there are at least 3 updates we released for this version since that time.
With PhpED v11 and v12, we ship dbg-6.0 and it's dbg-6.0.12 now.
Seems you have to update.
