Hi,
The problem is that FireSymfonyDebugData is a Javascript object, so
you need all the Javascript machinery around, I don't know it will
work with an XML document.
About the Headers, I have thought that already, but I don't know it
this is not to much data to send.
Maybe you can try with FirePHP perhaps. That extension works pretty
neat with Firebug sending the data into headers.
I would like to integrate the debug data in the headers, but I haven't
had the time to think the best way to do it. I saw that there is a
similar extension to FireSymfony but for ColdFusion, I think it sends
the data in the headers, I will check.
Thanks for the comments,
Cheers,
Alvaro
