The SRE-http http/1.1 web server

Abstract

SRE-http is a highly configurable http/1.1 web server for OS/2. With advanced features such as remote configuration, virtual hosts, caching and SSI; SRE-http is powerful enough for technically proficient administrators, but simple enough to be maintained by non-technical users. In addition, the Rexx based GoServe API (as augmented by SRE-http's numerous extensions) offers significant development advantages when creating web based applications, and when otherwise crafting a customized and enhanced web site.

To use the SRE-http web server, you will need GoServe (a free, IBM EWS, OS/2 Internet server).

Demos of a few SRE-http features.

The following examples scratch the surface of SRE-http's potential:

Try a simple server side image map ?
... or an <ISINDEX> searchable index (does any one still use them?)
Server side includes? How about a demonstration of
a potpourri of the NCSA-style server side includes,
another pottage of SRE-http style SSIs
"in-line code" execution using the INTERPRET keyphrase,
a simple example of SRE-http's use of cookies ,
With SRE-http's built-in procedures, it's easy to implement server-push
See what's in our PUBFILES area with SRE-http's directory display facility?
... or examine the contents of the SRE-http distribution file repository?
...or would you like to use our SWISH search-engine to search the SRE-http file repository, by filename or keyword?

The classic CGI-BIN/TEST-CGI
Simple demo of SRE-http's encryption of FORM elements.

When asked, use the following:username:GUEST,password:GUEST, and shared-secret:ENCTEST
