Hi, I am running haproxy v1.6.4, and I am attempting to block a specific request regex pattern. I am encountering issues with matching the question mark in the request. What I would like to block is requests that match this pattern: /api/.../.../sql?
I would like to include the question mark on the end of the "/sql" but I am unable to find a regex string that works for this in haproxy. I have tried the following ACL's which all worked in various regex testing sites (including ones specifically for posix regex, e.g. http://regjex.com): acl uri_sql path_reg -i ^/api/(.*)?/sql\?.*$ acl uri_sql path_reg -i ^/api/(.*)?/sql\\?.*$ acl uri_sql path_reg -i ^/api/(.*)?/sql[?].*$ If I remove the question mark and search for the following, the regex works fine, but I would like for it to be more restrictive. acl uri_sql path_reg -i ^/api/(.*)?/sql.*$ My deny line is as follows: http-request deny if uri_sql Can you please provide assistance?
