[syslog-ng] Syslog-NG to parse HTTP query strings?

Hello Is Syslog-NG capable of parsing HTTP query string key=value pairs? I've read through both the CSV and pattern DB parser documentation and it seems they both presume a consistent ordering in the $MSG field. Neither seem appropriate when if the order of query string pairs changes, such as: http://somehost.com/somefile.cgi?keyA=valueA&keyB=valueB or http://somehost.com/somefile.cgi?keyB=valueB&keyA=valueA Basically, I want to grab keyA's value irrespective of which order it appears and use it as a value in an SQL insert statement. Is this possible with Syslog-NG's native parsers or am I going to have to handle this in a Perl script/program? Cheers Steve
