Hi,

I am trying to setup reverse proxy for my internal business users for site validation when the external route is down. I am able to setup multiple routes with corresponding virtual hosts entries in httpd.conf for port 80 : anonymous user. Am afraid am stuck at SSL route and unable to make progress.

Configuration details:-

Apache version: Apache/2.2.29 (Unix) Linux Version: $ cat /etc/*-release Enterprise Linux Enterprise Linux Server release 5.8 (Carthage) Oracle Linux Server release 5.8 Red Hat Enterprise Linux Server release 5.8 (Tikanga)

When I try to access over SSL (*:443) I get empty response on all 3 browsers (IE/Chrome/Firefox). Below is the error log:-

When you use mod_proxy with Apache/Tomcat, Apache handles the SSL transport. The actual tunnel from Apache to Tomcat (via mod_proxy) is done in clear text, not encrypted.

Unless you're really paranoid or have set up a pretty questionable infrastructure, that's OK, since normally the Apache-to-Tomcat channel is either on the same machine (hence essentiall un-tappable) or at least behind the firewall, where the only security risk is from in-house snooping. Which a VPN can probably help with at the hardware level, it it's a concern.

Hi Tim,

I am not getting this ? are you telling the creation of self signed certificate might be a problem? how we can resolve this error ? Please clarify.

Thanks.

Hmmm. I just looked closer. Are you really doing a REVERSE proxy here? Your ProxyPass is to an external site.

And it's google.com which has gotten all righteous about using SSL ever since the NSA scandal.

Your message was "ttps proxy request speaking HTTP to HTTPS port!? " and that sounds about right if you did a proxy forward to google.com and it wanted https.

Thanks Tim, are you telling we need to change the reverse proxy as below with https for 443 instead of http?

ProxyPass / https://www.google.com
ProxyPassReverse / https://www.google.com


where for virtual host 80 we will have "http":-

ProxyPass / http://www.google.com
ProxyPassReverse / http://www.google.com

Please clarify.

Have you tried it?

I'm not sure if Apache will automatically encrypt properly or not, but at least you'd be addressing https instead of http. So if that doesn't work, I'd recommend google. I did some research on this general area about 2 months ago, but my conclusion was that I didn't want to bother with back-end software-based encryption. However, if you're querying google, you don't have that option.
