CGI scripting program for embedded environments
DescriptionHaserl is a CGI wrapper that allows PHP-style programming in Lua or a POSIX-compliant shell. It is very small, so it can be used in embedded environments, or where something like PHP is too big. It combines three features into a small CGI engine:
* It parses POST and GET requests, placing form-elements into the
environment as name=value pairs for the CGI script to use. This is
somewhat similar to the uncgi wrapper.
* It opens a shell, and translates all text into printable statements.
All text within <% ... %> constructs is passed verbatim to the shell.
This is somewhat similar to how PHP scripts are parsed.
* It can be set up to drop its permissions to the owner of the script,
giving it some of the security features of suexec or cgiwrapper.
