Trevor,

Have you checked MSDN or shellcity.org? 
They might have what you need...

bingo, somewhat...

ocol/automatic_web_proxy_detection.asp>

<http://www.wrec.org/Drafts/draft-cooper-webi-wpad-00.txt>

although - there's no info per say... Grrr

<http://msdn.microsoft.com/library/default.asp?url=/library/en-us/randz/prot
ocol/royalty_free_protocol_license_agreement.asp>

Has a list of many different protocols... it's a start. 

For php, i found this...

Maybe google has more but i didn't read the 419000 links it found ;)

Note that most "corporate" software distributes the settings required to run
in their network (SMS, Novell NetInstall, Octopus, etc...). Nothing you can
do about it other than ask the administrator to send you also that info...
Any of these systems can deliver a file to your users' folders. 

IMOHO, you should contact their network administrator for a settings file
delivery or their proxy setting delivery so you can adapt your software to
their network. Im not sure all proxy settings can be detected... Also, given
it's a multi-subnet lan, there's little way to know which lan the proxy is
in... So, haveing the same conditions at work, we're forced to enter it
manually. Most users however use preconfigured thin-clients where the
problem would  be the same for your application, and furthermore, your app
may not have access to the registry entries due to security restrictions.

cheers
