Web development behind a proxy server?

Hi,

The admin from a company I work for has changed some network configurations.

While I have all rights to access the internet via diff. ports I need to test my sites behind some proxy server (ISA Server).

I notice now that php scripts are cached and thats very disturbing during tests (the results are often teh same because I use the same test data)

Is there something else I need to accept to get in trouble behind that Proxy/ISA serrver?

What if you use some dummy get whenever you want to check a page?

For instance if instead of visiting site.com you can visit site.com/?a=123

Does this helps?

NO :(

I'm not looking for a work around (I'm able to use a sec. internet connection), I'm looking for arguments to tell the admin to do it different ;)

I think this is a bug. A proxy should check the LAST-MODIFIED headers before serving a cached page.

maybe its because the end of the summer time (there was a switch this weekend)
