iRule to log HTTP Request

Thanks for your answers.

I have almost made it... except for the date format.

Indeed the request logging profile is tampered with $DATE_NCSA variable which produce something like:

[11/Aug/2014:16:17:19 +0200]

With the iRule I use the following:

set req_start_time [clock format [clock seconds] -format "%d/%m/%y:%H:%M:%S %Z"]

which produces something like:

11/08/14:15:35:50 CEST

I do not know how to make them "match" (for the syntax)..

Thanks
