The tiny web server ... 400 Lines of code.
Build to be embedded in any ruby application, test/debug/admin access...
Features :
- methods GET POST (PUT, REMOVE, HEAD... are missing!)
- index generate as simple explorer (if path correspond to existant directory or file)
- multipart/data supported
- upload file via multipart
- multipart dynamic (can be active continiously, a timeout inter-part is setted to 10 minutes)
- http redirection
Performances are not so bad : better than Sinatra/Thin, near Puma/Thin)

endWith v2 API, all methods which name match get_()_() will be associate with url $1 and his output will be sending with MIME code corresponding to file extension $2.
So def get_login_html() while match for path /login,method GET or POST, end returned value is sended as Content-type: text/html
WebserverRoot.new(
port_http, # server http port (>1024 on posix, if not root)
root-dir, # only one file root. indexed by defalut
ws_name, # name in trace & index title
10,300, # watch too long connection: every 10 secondes,
# kill session which have started from more than 300 seconds
{} # options. only one, for logg events , see demo.rb
)Servlet receive params hash which content :
- all http header, with key upercase, prefixed with 'HEAD-'
- http parameters (?a=b&...)
Exemple : http://localhost:9980/info?aa=bb&cc=dd, give with p.to_a.inspect:
["aa", "bb"]
["cc", "dd"]
["HEAD-HOST", "localhost:9980"]
