I have an odd setup. It looks like this:
Browser ----------> HTTPs Proxy ------> Apache HTTP -----> Tomcat AJP HTTPS HTTP AJP
On the HTTPS proxy (a very dumb proxy), a URL comes in looking like https: //proxy.domain.com/app. It is then tunneled to Apache using HTTP as is http: //apache.domain.com/app (passing in the host proxy.domain.com). Apache then tunnels the request locally using the AJP protocol to ajp: //localhost:8009/app/.
Sometimes the app server wants to redirect the requested path. For example, redirect /app/ to /app/webapp. So, it sends a 302 back to apache redirecting the path - probably something like ajp: //localhost:8009/app/webapp. Apache then rewrites the redirect URL to http: //proxy.domain.com/app/webapp. The HTTPS proxy is dumb, so it does not analyze the redirect and change the http to https.
So, I would like to figure out if I can configure Apache to re-write the 302 redirect URL to send the user to https.
Here is the config I have so far in Apache's https.conf:
ProxyPreserveHost on RewriteEngine on RewriteRule ^/app$ /app/ [PT] ProxyPass /app ajp://localhost:8009/app
I tried using ProxyPassReverse, but haven't been able to figure out how to force it to rewrite the 302 redirect URL with https instead of http.
