Our problem is that the html portal logon page generates absolute urls to resources like http://external-host/com.sap.portal.epcf.loader/... As you can see it is dropping the url-prefix. So our pages are not displayed properly and forms cannot be submitted.
Is there a way to tell the url generator to put a prefix into each generated absolute url?
Easiest way is to map /, the more tedious one is to list all the prefixes that need mapping. Depending on what resources you access on AS JAVA, the list can grow significantly (mine in the past had about 10 entries).
Do you mean to map all requests received on our reverse proxy to and beyond / to our SAP Portal? This won't work because the reverse proxy serves some more web applications and not only the sap portal. To map / would break other applications (ruby, static sites, etc.) which are also served.
Anything is possible. A recommended configuration would be for you to setup DNS aliases for all of your applications (SAP Portal, Ruby, etc.). That way you can have virtual host specific reverse proxy mappings. Believe me, it will pay off. Having a non-standard configuration means you will have to implement tweaks here and there not to mention how painful it is to maintain such a configuration.
Still, if you want to try it out try the following configuration
Apache will use URL prefix /app2 for any URL generated by AS JAVA. That said, you will run into problems eventually since URLs get generated in so many ways, including URLs within HTTP responses which Apache will not change.

Yeah, that's what we have done on other sites. But it has the drawback that you have to get seperate ssl-certificates (extended validation) for each domain or have to update the existing ssl-certificate with additional dns-aliases.
So we tried on this site to sepearte each application by url-prefixes. So each application is covered by the same certificate.

That's our problem now. Apache does map the url from http-request but the http-response-content from sap-portal is untouched. So absolute links within html pages generated by sap-portal are pointing to the wrong path. Protocol, host and port are correct but the path is missing the url-prefix.
So i don't want our apache to correct the links and rather want sap-portal to produce correct links. It's working fine with protocol, host and port for urls, but i can't set an url-prefix for the path-component.
So my hope is that you can make the url generator from sap portal aware of our url-prefix (maybe depending of virtual host, or by setting a field in http-request) like it's aware of incoming protocol, host and port. So that every generated link will get an url-prefix for it's path component.
