Hi all, After I made the 0.0.0 release of http-enumerator, Vincent Hanquez informed me of his wonderful tls package[1]. I've just release version 0.0.1 of the http-enumerator package which will use the tls package by default for establishing SSL connections. If you still want to use the OpenSSL package, just give cabal the build flag openssl, ie: cabal install -fopenssl http-enumerator The only other change to happen in this release is a modification to the chunked encoding parser to allow whitespace after the size of chunks. I think the HTTP spec does not mention that whitespace, but yahoo.com uses it. As before, consider this experimental, please try it and give me feedback. Cheers, Michael [1] http://hackage.haskell.org/package/tls
