[users@httpd] Help with setting up proxy

Hi everyone,

	I need a little assistance setting up a Reverse Proxy on Apache 2.0.59

	Situation
	--------------
	I have a server 172.16.0.141 which hosts our website.
	This website sources Adverts from another server 172.16.2.150

	I want to set up a proxy server on 172.16.0.141 so that the original website will link through to itself. to get these adverts.

	i.e. when I call 172.16.0.141/adverts this will proxy through to 172.16.2.150/adverts

	The server 172.16.0.141 has an https certificate which we use for login
	The server 172.16.2.150 does not have https certificate.

	I have set up the following so far in my httpd.conf

		-------------
		ProxyRequests off
		ProxyPass /adverts/ http://172.16.0.141/adverts/

		<Location /adverts/>
		        ProxyPassReverse /
		</Location>
		-------------

		But when I hit 172.16.0.141/adverts/default.aspx I get the following error:
Proxy Error

The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /adverts/default.aspx.

Reason: Max-Forwards has reached zero - proxy loop?


	What am I doing wrong ?
	And how can I cater for https calls on the original web server, being routed through to the un-secure web server without a warning to the end user?

	Many thanks

Regards

Mark

Your ProxyPassReverse is gibberish. Replace with this:

<Location /adverts/>
    ProxyPassReverse http://172.16.0.141/adverts/
</Location>

Which is equivalent to the shorter version (no location block):

ProxyPassReverse /adverts/ http://172.16.0.141/adverts/

You'll need to elaborate on what you mean there.

Cheers
