Re: Proxy HTTPS tunneling (Apache Users)

Are you trying to set up a Forward Proxy or a Reverse Proxy (explanation: http://www.jscape.com/blog/bid/87783/Forward-Proxy-vs-Reverse-Proxy)?

Your configuration looks like a forward proxy but your email implies that you really want a reverse proxy.

See this part of the HTTPD manual for more about reverse proxy setup: http://httpd.apache.org/docs/2.2/mod/mod_proxy.html#forwardreverse

A reverse proxy is activated using the ProxyPass directive or the [P] flag to the RewriteRule directive. It is not necessary to turn ProxyRequests on in order to configure a reverse proxy.

Hello

WE are trying to setup HTTPS tunnelling to a backend server through Apache proxy but we are finding the client connect but Apache does not send through the traffic the backend server.

The config we have on our Apache proxy virtual host is

<VirtualHost 172.19.1.136:443>

DocumentRoot "/usr/local/apache2221/htdocs/ibcm/"

ServerName test.testdom.local

ErrorLog logs/ibcm

ServerAdmin webmaster@testdom.local

ProxyRequests On

AllowConnect 443

SSLEngine on

SSLHonorCipherOrder On

SSLProtocol -ALL +SSLv3 +TLSv1

SSLCipherSuite ALL:!aNULL:!ADH:!eNULL:!LOW:!EXP:RC4+RSA:+HIGH:+MEDIUM

SSLCertificateFile "/etc/ssl/crt/ibcm.crt"

SSLCertificateKeyFile "/etc/ssl/crt/testdom.key"

SSLCertificateChainFile "/etc/ssl/crt/CA-DOM.crt"

<proxy *>

   Order deny,allow

   Deny from all

</proxy>

<ProxyMatch (webssl.testdom.com|192.168.50.100)>

   Order deny,allow

   Allow from all

</ProxyMatch>

</VirtualHost>

Anybody know what we are not doing correctly.   Also we found Apache would not start without us putting in the root certificate. Thought it would not need any certificate for tunnelling so wonder if we have missed something.
