It would be very nice to have a common format. Historically HAppS has used ByteStrings in HTTP, while most other libraries have used Strings.

But moving from [ByteString] into a lazy ByteString makes sense. - Einar Karttunen ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

I seem to have duplicated Tim's efforts before I noticed this thread. In order to keep this from happening again, I have put up a darcs repo at http://darcs.haskell.org/hws/ It contains the version from fptools-hws (http://cvs.haskell.org/cgi- bin/cvsweb.cgi/fptools/hws/) with the following modifications: - Use the hierarchical libraries. - Use Data.Map instead of FiniteMap. - Use Parsec from the hierarchical libraries and removed the included old parsec copy. - Removed ifdefs for compatibility with GHC 4.x and 5.x (they wouldn't work with the new imports anyway). - Use IOUArray in Response.squirt - Use Cabal for the build system. It now builds with GHC 6.4.1 and GHC 6.5 (if you add html and regex- compat to the build-depends). If any of you have any other updates, bugfixes etc., you are welcome to add them. Maybe we can even get Simon Marlow to update it with the current state-of-the art in high-performance concurrent Haskell? I'm thinking that we should try to keep this version reasonably close to Simon's original version, or at least its intent, and work on extra features in separate branches. /Björn___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

Btw. would it be possible and sensible to use the same Response and Request data structures both for the client module Network.HTTP and the Haskell Web Server?
