I've tried the example on apachetutor (http://www.apachetutor.org/admin/reverseproxies) as it seemed like exactly what I wanted but it's not quite working.
What I have is a single DNS entry that I want to then put multiple websites behind. So for example:
DNS = help.mydomain.com
All this code is inside a VirtualHost block:
| Code: | <VirtualHost *:443>
ServerName help.mydomain.com |
I have a tomcat server that I've mapped to a single app successfully because it's using the same URL:
| Code: | ProxyPreserveHost on
ProxyPass /app1 https://10.10.1.2:8443/app1
ProxyPassReverse /app1 https://10.10.1.2:8443/app1 |
The above works like a champ because the /app1 is literally there on both sides. What I now need is an uneven match. So based on the tutor example I then tried a proxy for a standard webpage that the server hosts at the root level, but want to proxy it by another sub url:
| Code: |
ProxyHTMLExtended On
ProxyRequests Off
ProxyPass /app2 https://10.10.1.50
ProxyHTMLURLMap https://10.10.1.50 /app2
<Location /app2>
ProxyPassReverse /
ProxyHTMLEnable On
ProxyHTMLURLMap / /app2
RequestHeader unset Accept-Encoding
</Location>
|
When I go to help.mydomain.com/app2 it manages to see the initial page enough to redirect to the home.html page. But the address bar gives me:
| Quote: | | help.mydomain.com/home.html |
When I'm expecting:
| Quote: | | help.mydomain.com/app2/login.html |
If I put the /app2 in there it finds enough to have the next forward to work (meaning you hit home unauthenticated so it directs you to the logon script then to a login page, etc...) but each time it goes to pull the new page the URL keeps dropping the app2 portion.
How do I fix this? I've tried a redirect call but depending on security settings, that gets caught by the user's browser but then it's also a non-routable IP so I realized it won't work anyway.
Thanks for your time. |

From the tutorial you missed the trailing slash at the end
ProxyPass /app2 https://10.10.1.50/
Maybe also helpful from Version 2.1, mod_proxy_html supports a ProxyHTMLLogVerbose directive, to enable verbose logging at LogLevel Info.
When verbose logging is enabled, the following messages will be logged:
- In Charset Detection, it will report what charset is detected and how (HTTP rules, XML rules, or HTML rules). Note that, regardless of verbose logging, an error or warning will be logged if an unsupported charset is detected or if no information can be found.
- When ProxyHTMLMeta is enabled, it logs each header/value pair processed.
- Whenever a ProxyHTMLURLMap rule matches and causes a rewrite, it is logged. The message contains abbreviated context information: H denotes an HTML link matched; E denotes a match in a scripting event, C denotes a match in an inline script or stylesheet. When the match is a regexp find-and-replace, it is also marked as RX.
