[opencms-dev] "Multiple Site without, /opencms/opencms/" using Apache for static content

[Bernd Wolfsegger]

Hi Peter,

one remark on static content feature:

If requests to /export are not handled by opencms, no files form the VFS will 
ever be copied to the RFS so that they can be used as static content in 
further requests (originally there is no static content). So the "static" 
content functionality will only work if at least /export requests run  
through opencms.
Eg if you have images in opencms in the resources folder in your module, they 
will be copied to the filesystem when they are requested for the first time.
But if the /export request does not run through tomcat/opencms they are never 
copied to the filesystem and they will be served from the database always.

Other content that should not be handled by tomcat:
Isn't it possible to achieve the same with:

PropyPass /dir_html !

This has to be put in front of all the other ProxyPass directives.

And for the aditional webapp, you need only the lines:

ProxyPass         /dir_webapp/               http://localhost:8089/dir_webapp/
ProxyPassReverse  /dir_webapp/               http://localhost:8089/dir_webapp/

and than the rest of the ProxyPass directives.

I see no reason why to use the Rewrite engine, but though I have not tested 
the rewrite solution I can see no drawbacks either. :)

Well and I will test this other new mod_jk solution from
Sebastian Himberger when it is posted.
It's always good to have different working solutions for the same problem.

Kind regards, Bernd
