AllegroServe - a Web Application Server.
Edit By BS Editor: AllegroServe has these components:

* HTTP/1.1 compliant web server capable of serving Static and dynamic pages
* HTML generation facility that seamlessly merges html tag printing with computation of dynamic content. The Html Generator matches perfectly with the HTML Parser (which is in another project) to allow web pages to be read, modifed in Lisp and then regenerated.
* HTTP client functions to access web sites and retrieve data.
* Secure Socket Layer (SSL) for both the server and client.
* Web Proxy facility with a local cache.
* Comprehensive regression test suite that verifies the functionality of the client, server, proxy and SSL
* high performance for static and dynamic web page delivery
* Licensed under terms that ensure that it will always be open source and that encourages its use in commercial settings.
* A new publish function that builds a page from static and dynamic data and handles caching of the result.
* Access control mechanisms for publishing directories that gives the webmaster the ability to specify which files and directories in the tree should be visible.
* The ability to run external CGI programs.
* An improved Virtual Hosting system that supports different logging and error streams for each virtual host. you can free download AllegroServe 1.2.56 now.
