Hello,
In happstack, there is a Writer monad which holds a list of filters
which will be applied to the Response before sending it out. One of
these filters is the gzip filter.
The compression filters are defined here:
Hey Jeremy,
I was just wondering: how does Happstack deal with gzip encoding when it
uses sendfile? I can think of a few ways (cache gziped versions to the
disk), but was wondering if you'd already come up with a good solution. I'm
trying to keep all these things in mind when designing WAI.

Absolutely; the goals I have are minimal dependencies and no warnings for
compilation ;).

Hi Michael,
no, the message was not meant to be off-list, that was just me
pressing the wrong button :-)
Regarding happstack, I do not believe that there is a contrast with
your effort, the core of happstack is in its persistency mechanism not
in its http interface so I think it would be great

Hyena is especially tuned for streaming and that's exactly what hack
can't do (in practice).
Isn't possible to stream an (almost) infinite bytestring trough hack?. I
ever trough that the laziness of haskell is a great advantage in Web
applications.

Well, for one thing, you'd need to use lazy IO to achieve your goal, which
has some safety issues. As things get more and more complex, the
requirements of lazy IO will continue to grow. This also has implications
for number of open file handles

Hello,
Happstack is currently bundled with it's own lazy I/O based HTTP
backend. Ideally, we would like to split that out, and allow happstack
to be used with that backend, hyena, or other options.
A primary using for using hyena would be for the benefits of
predictability and constant

What hyena tries to solve can't be realized in hack, so there's not
too much reason for a backend anyway.
