For logging you can use %f (which is already there) although in some places fetcher is required and then you are stuck. BTW: Once I can "extract" frontend name is there a way to compare "dynamic" data (eg. frontend name) with another "dynamic" data (eg. host header) ? From what I can see we can easily compare "dynamic" data with "static" data (eg. some predefined string), but not eg. 2 variables. Regards,
Marcin Side note: In docs/configuration.txt I came across this: fe_id : integer Returns an integer containing the current frontend's id. It can be used in backends to check from which backend it was called, or to stick all users coming via a same frontend to the same server. shouldn't this contain: ...It can be used in backends to check from which FRONTEND it was called... ?
