I'm using Apache 2.4.7
I'm currently running and old Apache with customized software and need to change to using a newer Apache.
How do I parse out the server from the request and send the request to the process running on that server (and fixed port)?
Any help is greatly appreciated.

A request can come into an Apache running on one server and the request needs to be sent a process running on a different server.
We are using fixed ports and the port in the examples is 1234.
The process that should get the request is derived from the sessionid.
I need to parse out the server and send the request to the process running on that server.
Messages come in with GET or POST and /WebZ/...
Somewhere in the message is sessionid=<server>-<1234>-<...>-<...>
Some requests might have multiple '?' characters.
Some requests might not have any '?' characters.
Here are some example requests.
GET /WebZ/MEdit?sessionid=server09.prod-1234-kgv44z4b-pl2l93:editsessionid=2:catpage=html/corc/catalogue.html:entitymytemplateName=marc?sessionid=server09.prod-1234-kgv44z4b-pl2l93 HTTP/1.1
GET /WebZ/html/corc/helpredirect.html:sessionid=server02.prod-1234-kgvvyfoc-c7bsf2?/WebZ/html/corc/helpredirect.html:sessionid=server02.prod-1234-kgvvyfoc-c7bsf2?http%3A//www.oclc.org/bibformats/en/fixedfield/dtst.html HTTP/1.1
GET /WebZ/html/catexpress/CatExpressBasicSearch.html:sessionid=server09-1234-kgufwyh9-k6bak2:dbname=WorldCat HTTP/1.1
In my httpd.conf file, I have tried several combinations of RewriteCond, RewriteRule and ProxyPassMatch.
The sessionid is typically after the '?' and ProxyPassMatch doesn't find it.
The regular _expression_ below will parse out the server and put it into group $4
/(WebZ)/(.*)(.*?sessionid=([^-]+)-1234)(.*)$
For:
/WebZ/MEdit?sessionid=server09.prod-1234-kgv44z4b-pl2l93:editsessionid=2:catpage=html/corc/catalogue.html:entitymytemplateName=marc?sessionid=server09.prod-1234-kgv44z4b-pl2l93 HTTP/1.1
We would get:
Group 1. 5-9 WebZ
Group 2. 10-136 MEdit?sessionid=server09.prod-1234-kgv44z4b-pl2l93:editsessionid=2:catpage=html/corc/catalogue.html:...
Group 3. 136-164 sessionid=server09.prod-1234
Group 4. 146-159 server09.prod
Group 5. 164-189 -kgv44z4b-pl2l93 HTTP/1.1
