Hi,

is there any way to ship around the limitation that only a single  
`sub_filter` directive is supported per location?

In fact I want/need to replace 3 “strings” (/fileadmin/, /typo3conf/  
and /typo3temp/) within my root-location and “move” the requests over  
to absolute servernames (like a cdn) by the time the response is  
running through my frontend lb.

Any ideas how to accomplish that?

Regards,  
Christian
