Hey

How do i set the HTTP Error Code Header when using webrick.

I found the response.set\_error function. What do i need to pass there to  
e.g. set a http 404 error?

thx

Use raise to set status in WEBrick. For example,

require “webrick”  
s = WEBrick::HTTPServer.new(:Port =\> 2000)  
s.mount\_proc(“/”){|req, res|  
res.body = “ok”  
raise WEBrick::HTTPStatus::OK  
}  
s.mount\_proc(“/404”){|req, res|  
raise WEBrick::HTTPStatus::NotFound  
}  
trap(“INT”){s.shutdown}  
s.start

This server returns 404 for [http://localhost:2000/404](http://localhost:2000/404)  
but return 200 for other urls.

HTH,

Gotoken
