Apache Location Reverseproxy URL not working - regex

Question

I'm trying to match a URL with multiple params and use reverse proxy to load some other content, for some reason the Location Tag isn't working.
Following is my httpd.conf file
<Location "/tracker/">
ProxyPass "http://website.com:8290/track.js"
ProxyPassReverse "http://website.com:8290/track.js"
Order allow,deny
Allow from all
</Location>
<Location "/tracker/csc-event?p=([^\s]+)&s=([^\s]+)&v=([^\s]+)&e=([^\s]+)&c=([^\s]+)&n=([^\s]+)&f=([^\s]+)&l=([^\s]+)&i=([^\s]+)&j=([^\s]+)&k=([^\s]+)&w=([^\s]+)&h=([^\s]+)&t=([^\s]+)&x=([^\s]+)">
ProxyPass "http://website.com:8290/csc-event?p=([^\s]+)&s=([^\s]+)&v=([^\s]+)&e=([^\s]+)&c=([^\s]+)&n=([^\s]+)&f=([^\s]+)&l=([^\s]+)&i=([^\s]+)&j=([^\s]+)&k=([^\s]+)&w=([^\s]+)&h=([^\s]+)&t=([^\s]+)&x=([^\s]+)"
ProxyPassReverse "http://website.com:8290/csc-event?p=([^\s]+)&s=([^\s]+)&v=([^\s]+)&e=([^\s]+)&c=([^\s]+)&n=([^\s]+)&f=([^\s]+)&l=([^\s]+)&i=([^\s]+)&j=([^\s]+)&k=([^\s]+)&w=([^\s]+)&h=([^\s]+)&t=([^\s]+)&x=([^\s]+)"
Order allow,deny
Allow from all
</Location>
When I hit: https://website.com/tracker it works fine
But not with the other location, for eg If I hit:
https://website.com/tracker/csc-event?p=0%3Ajodv6q8w%3AdO9XGf6T4SCq7kz49hEEUwNvmkqR8Wxw&s=0%3Ajodv6q8w%3AHgkFFmKSZqdBB6E2C~F8xBKTHv8CGwbl&v=0%3AJ1gADq10d3pj1JL1lh4Dd7ZlLxQyl2~_&e=0%3AJ1gADq10d3pj1JL1lh4Dd7ZlLxQyl2~_0&c=jodvqubo&n=f&f=f&l=https%3A%2F%2Fwebsite.com%2F&i=11y&j=k8&k=1&w=mj&h=i9&t=pageView&x=-e1v043
It shows page not found error. What am I doing wrong? Is there some problem with regex or some other config problem?

Answer 1

If you want to use regex in a location directive you should add a tilde (~), but even then Location does not match the query string. Add /tracker/csc-event as a Location and check the query string inside that directive.
Also, proxypass preverses the query string, no need to add it.
