Hello. Yesterday I hit a bug in Network.Browser: connection in the connection pool is not reused if you are connecting to a destination with qualified port (not 80 for HTTP or 80 but explicitly provided like http://www.google.com:80). The reason for the failure is quite trivial, but I had not found an easy fix which won't break anything. Problem is that in TCP.hs function isTCPConnectedTo :: HandleStream ty -> String -> IO Bool isTCPConnectedTo conn name = do v <- readMVar (getRef conn) case v of ConnClosed -> return False _ | map toLower (connHost v) == map toLower name -> catch (getPeerName (connSock v) >> return True) (const $ return False) | otherwise -> return False socket's hostname, (connHost v) is compared to hostname or hostname:port which is stored in name. Hope this message will reach this code maintainers Alexander
