apache reverse proxy

wildbob · 10-09-2003, 12:02 PM

Hi,
I'm running apache on RH9 and need help with reverse proxy. I also have a networked web cam (built in web server on 192.x.x.x address). Let's say that my domain is xxx.yyy.zzz. I'd like requests for xxx.yyy.zzz/camera to go to the internally addressed webcam server. The Documentation that I've been able to find is confusing and I belive the proxy module names are different. Ok, so, I have apache running with only the stock installed modules and I'm not sure if the proxy modules are loaded by default. If somebody could let me know what modules need to be loaded and maybe a sample http.conf, ProxyPass setup...ReverseProxyPath setup. BTW--DSL(staticIP)-->Linux(IPMASQ)---->internal 192.168.0.x network...

THANKS,
WildBob

Have you looked at using mod_rewrite to do this?

No stickman, I have not.
Being fairly new to LINUX, I am unsure of the proper approach, so I've not chosen a method yet. If there was a "linux School" I'd be on the short bus...Will mod_rewrite do the trick? If so, please point me to some docs or include some sort of sample http.conf so I can see what's going on. THANKS for the quick response!!!

The URL Rewriting Guide on the Apache site should give you enough examples to get you started.

OK, Thanks.....

Is it Dynamic Mirror that I want to use? Would this be correct:

RewriteEngine on
RewriteBase 192.168.0.8/
RewriteRule ^/(.*)$ http://x.y.z/camera$1 [P]

Remember http://x.y.z/camera is where I want people to go and the internal address is the camera.

Forgive me as I stumble through this..........

I would use a RewriteRule similar to:
RewriteRule ^/camara(.*) http://192.168.0.8/path/to/$1 [P,L]

where ^/camara(.*) is the match condition that gets proxied to the internal address. Anything after camara (ie .*) will be filled into $1. You may need to tinker with the match condition to get the effect you want.

Hmmm..does this go in httpd.conf? I get this error:
httpd failed. The error was: Stopping httpd: [FAILED]

Starting httpd: Syntax error on line 893 of /etc/httpd/conf/httpd.conf:
RewriteBase: only valid in per-directory config files
[FAILED]
