Post processing with Perl?

[Iikka Niinivaara]

Hi guys,

I'm trying to do some fairly complex post processing to the body of a  
response of a proxied request. Since sub_filter only supports one  
rule per location and doesn't support regexp's at all (why hasn't  
anyone fixed this?), I'm looking at using the embedded Perl  
functionality to do what I want. To my disappointment, I couldn't see  
any info about post processing the client body in the documentation.

Can anyone tell me if this is possible at all, and if so, give me  
some pointers to get started?

Thanks,
Iikka
