If you use Zend toolbar for FireFox together with Zend Studio, there is one thing that you may want to know.
If you enable proxy in browser settings, toolbar may fail to connect to Zend Studio. The reason for this is that Zend toolbar uses XHHTPRequest to issue GET request to Zend Studio to obtain configuration parameters. Normally Zend Studio returns something like:
HTTP/1.1 200 OK
Content-Type: text/html
&debug_port=10000&debug_host=192.168.239.1
%2C192.168.184.1%2C192.168.1.155%2C127.0.0.1&
use_tunneling=0&debug_fastfile=1
(This is easy to check with telnet!) But if you enable proxy, XHHTPRequest will attempt to connect to 127.0.0.1 through proxy and most likely will get error 403 (Forbidden) back. As a result Zend toolbar will say that it cannot autodetect ZDE settings on port 20080.
The solution is to write 127.0.0.1 as exclusion to proxy connections in advanced proxy configuration.
All above was found while looking into JavaScript file from Zend toolbar, which is available in FireFox profile folder.
