tcp80x

tcp80x is an HTTP server with some pseudo-CGI support.
This is a merger of execfs and tcp80, both written by cinap_lenrek.

Install with mk install
Create a /rc/bin/service/tcp80 file:

#!/bin/rc
exec /bin/tcp80x -r /path/to/rules

tcp80x handles request as follows:

1. Parse the request location
2. Try to match the location against defined rules
3. If a rule matches, execute the associated command line (see Rules)
4. If not, look for a matching file in /usr/web and serve it

NB:

• Unless -t flag is passed to tcp80x, /usr/web is bound to / before serving static files.
• For scripts to work properly, they need to return a proper HTTP response.

The rules file is used to match incoming requests against a regular expression and if a match is found execute the command associated with the regular expression. The format is:

# Comment
tn

The command line is transformed with regsub(2) meaning that it can contain references to matches in the regex in the form 'n' where n is a digit.

First we create a rule file:

/hello/([^'/]+)	/bin/hello '1'

Then, a hello script:

#!/bin/rc
rfork en
echo 'HTTP/1.1 200'
echo ''
echo 'Hello '^$1

We can now browse to http://s*e**rver/hello/bob which should be displaying 'Hello bob'.
