Performance Logging iRule (Rule_http_log)

I found that this upvar statement doesn't work (it crashes later when entering the foreach loop):

upvar 1 $mylog log

From what I understand, you're passing "log" already as a parameter to the hsllog proc and then do a reference from $mylog (which should be a copy of log?) back to yourself? ​I can't wrap my head around that. Any way I changed the name of the "log" variable inside hsllog proc to "alog", i.e. "upvar 1 $mylog alog" and used alog in the foreach loop instead. That works as expected…

Also you can check http2 version by using this instead:

 if {[HTTP2::version] != 0} {

       set log(http_version) [HTTP2::version]

   } else {

       set log(http_version) [HTTP::version]

   }

Kind Regards,
