Haskell library for building Internet applications

HAppS is a Haskell library for building industrial strength Internet applications safely, quickly, and easily. With HAppS you focus entirely on application functionality implemented in Haskell and you don't have to worry about making sure all sorts of server subsystems are functioning properly.

 - HTTP Application Server
   Performs better than Apache/PHP in our informal benchmarks
   (thanks to FastPackedString), handles serving both large (video)
   files and lazy (javascript) streaming, supports HTTP-Auth, and more.
 - Mail delivery agent with integrated DNS resolver
   Stop worrying about making sure a separate local mail server or DNS is
   up and running to delivery your mail. HAppS takes care of making sure
   your mail is delivered as long as your application itself is running
   and makes sure no outbound mail is lost even with unplanned restarts.
 - XML and XSLT
   Separate application logic from presentation using XML/XSLT. With
   HAppS, you can have your application output XML (via HTTP or SMTP) and
   handle style/presentation via separate XSLT files at runtime. HAppS
   takes care of doing server side XSLT for outbound mail and HTTP
   user-agents that don't support it client side.
 - SMTP Server
   Handle incoming email in your application without worrying about
   .procmail or other user level inbound mail configuration hackery. Just
   have the HAppS.SMTP listen on port 25 or have the system mail server
   SMTP forward mail for your app to some internal port.
 - Monadic ACID transaction service
   Write apps as a set of simple state transformers. MACID write-ahead
   logging and checkpointing make it easy for you to guarantee
   application integrity in the face of unplanned outages. MACID even
   guarantees that your side effects will be executed at-least-once if
   they can complete within a timelimit you define.
 - Session Service
   Define bits of per-user application state that automatically expire
   after time limits you define. No more manual housekeeping of session
   data!
 - (Experimental) Table and Index
   Do relational operations safely on in memory Haskell Data.Set(s)
   rather than dealing with an external SQL relational database. Define
   custom indices for your Haskell datatypes (e.g. geographic/geometric
   types). Use in combination with MACID for a robust relational DBMS
   customized for your application.
