What is haserl

haserl is:

Haserl 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.
