Need help with Apache Reverse Proxy, webcams

[Yu Meng Chong]

Hi all, 

I'm trying to use Apache as a reverse proxy for a bunch of webcams at a customer site, and I need some help (of course!)...

The webcams' video feeds are accessed via web browser, but the user (viewer) needs to login first before getting to the video page. So, the viewer goes to http://cameraHostname and logs in. He is then redirected to http://cameraHostname/tgi/login.tgi

I have configured Apache as a reverse proxy so that the webcams' video feeds can be accessed from outside the network and they are mapped like so:
Requests to http://webserver/ipcam1 go to http://cameraHostname/

This displays the login page, but once I enter the username and password, I am brought to http://webserver/ipcam1/tgi/login.tgi, which should be correct, but instead gives me a 404 error. 

Does anyone here have any experience with webcams and Apache reverse proxying? Would really, really appreciate any advice ...

Thanks in advance,
