I am having difficulty creating a new mod security 2.5 rule.
My deployment: Apache server, Setup as a reverse proxy. (so the apache webserver __does not_ host the website. Instead, I proxy the requests to another server that answers the web requests.)
The web server uses authentication tokens to rewrite the website URL to a secure URL.
75.75.75.75 - - [01/May/2015:10:55:14 -0400] "GET /record/example.svc/js HTTP/1.1" 200 1786 "https://example.org/example.aspx?XOW%5eLdz%3c2%2f1%2f42%2527kbmhtbffJfx%3e0%2527qpkf%5ejc%3e2%2527Cfruho%60uhpmXOW%5eLdz%3c2%2f1%2f42%2527RptsbfVQU%60Jfx%3e193%2527qpkf%5ejc%3e2%2527RptsbfVQU%60Ejqts%60Bihmc%60Mblf%3cSdrtfru%1fTbpqjmh"
The Problem:
Modsecurity currently scans the URI. Due to the nature of the random URIs, a lot of false positives have been produced. To prevent this, I want to exempt all URIs from scanning.
Since the rewrite, redirect and authentication token are all being generated on the webserver (And this how we want to keep it), how do I inform mod security that these headers are legitimate and do not scan them?
