modperl_filter_t question
Hi,

modperl_filter_t contains 2 bucket brigades:

apr_bucket_brigade *bb_in;
apr_bucket_brigade *bb_out;

Each time a filter is invoked a new modperl_filter_t structure is created by
modperl_filter_new. This function sets either bb_in or bb_out bit not both.

It seems to me that it is not possible that both fields are used at the same
time since the result of modperl_filter_new is either an output or an input
filter but not both.

So, why are there 2 fields?

Am I missing something?

Yes, I believe you are, but I don't have time to decipher it myself either.
