Running click behind an Apache proxy

[Br...@csiro.au]

Hi

I have just started using Click - excellent framework.  I have an application up and running but I have run into an issue running the application behind a proxy.  This article sets out how a proxy is setup - http://www.apachetutor.org/admin/reverseproxies.  I have followed these instructions to test this locally but the application fails in two ways.  The html resource urls are broken - using mod_proxy_html fixes this but I consider that a hack.  The redirects fail.  Apache Wicket appears to address the whole issue, according to this article - https://cwiki.apache.org/WICKET/wicket-behind-a-front-end-proxy.html - I am currently using the SpringClickServlet but, it doesn't appear to have anything like contextpath.

Thanks
Brad

RE: Running click behind an Apache proxy

Thanks Fredrik.  The problem occurs when the proxy is not limited to the domain (I hope the terminology is correct), e.g. http://my.domain.com/xxxxx/myapp

I am using Apache Httpd and Tomcat.  

As always, talking to someone helps!

The following https.cong configuration works:

ProxyPass /xxxxx/myapp http://myserver:8080/xxxxx/myapp
ProxyPassReverse /xxxxx/myapp http://myserver:8080/xxxxx/myapp
ProxyPassReverseCookiePath /xxxxx/myapp /

I found that I also needed to change the tomcat server.xml configuration as well:
<Context docBase="myapp" path="/xxxxx/myapp" reloadable="true"/>

Thanks again!
Brad

I have used Click in environments where Tomcat runs on localhost and is fronted by apache httpd, proxied through mod_proxy. There is nothing particular to Click that makes it more or less suitable for that kind of configuration than any other web framework.

Basically all you need is something like this:

 ProxyPass /clickapp http://localhost:8080/clickapp  ProxyPassReverse /clickapp http://localhost:8080/clickapp

Can you post the relevant parts of your site configuration in Apache?
I assume Apache Httpd and Tomcat, but maybe that isn't your setup?

BTW, I do not recall ever needing to use mod_proxy_html, if you use relative url:s - and I belive click does that by default - you won't have any absolut urls in the html documents that needs rewriting.
