Subject filtered I/O - flow control
Date Thu, 01 Jun 2000 17:44:22 GMT
How would flow control work with each of the proposed filter designs?

Suppose we have I want to use a mod_include filter to put a header and
trailer around the new-httpd mail archives for April, use mod_php to
filter out junk from the mail headers, then put it on the wire.  The
socket isn't likely to swallow all of that data in one gulp.  So how do
the filters wake up once the socket is ready to write again, and where
does the data sit in the mean time?
