Hello, HAppS - Haskell Application Server version 0.8 has been released and contains a complete rewrite of the ACID and HTTP functionalities. Features include: * MACID - Monadic framework for ACID transactions: 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. * HTTP Server: Performs better than Apache/PHP in our informal benchmarks (thanks to Data.FastPackedString), handles serving both large (video) files and lazy (javascript) streaming, supports HTTP-Auth, and more. * 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. * Mail delivery agent Stop worrying about making sure a separate local mail server or DNS is up and running to deliver 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. * DNS resolver in pure Haskell For resolving MX records and concurrent queries. Can use an upstream DNS server or root servers directly. * 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. * Sessions and much more!
