[Haskell-cafe] Bits and pieces needed to build a web server

I've got an idea for a web server model I would like to try and since I'm quite new to Haskell it would be great if someone could enumerate a couple of useful libraries to me. Here's what I need (I've put what I've found so far inside parenthesis): * Parsing of incoming HTTP request and creation of replies (http://www.haskell.org/http/) * XML parsing and generating (http://www.cs.york.ac.uk/fp/HaXml/) * Database support (mainly SQLite but perhaps also MySQL/PostgreSQL) (There seems to be several options for this one. I don't know the names of the table nor the columns at compile time so I need something that doesn't require that.) A big plus if the library is still being developed/maintained. Thanks in advance.
