This handler allows you to redirect one url to another. You can use it like String#gsub, where the string is the REQUEST_URI. REQUEST_URI is the full path with GET parameters.
Eg. /test/something?help=true&disclaimer=false
h = Mongrel::HttpServer.new('0.0.0.0') h.register '/test', Mongrel::RedirectHandler.new('/to/there') # simple h.register '/to', Mongrel::RedirectHandler.new(/t/, 'w') # regexp # and with a block h.register '/hey', Mongrel::RedirectHandler.new(/(\w+)/) { |match| ... }
You set the rewrite rules when building the object.
pattern => What to look for or replacement if used alone
replacement, block => One of them is used to replace the found text
# File lib/mongrel/handlers.rb, line 446 446: def initialize(pattern, replacement = nil, &block) 447: unless replacement or block 448: @pattern, @replacement = nil, pattern 449: else 450: @pattern, @replacement, @block = pattern, replacement, block 451: end 452: end
Process the request and return a redirect response
# File lib/mongrel/handlers.rb, line 455 455: def process(request, response) 456: unless @pattern 457: response.socket.write(Mongrel::Const::REDIRECT % @replacement) 458: else 459: if @block 460: new_path = request.params['REQUEST_URI'].gsub(@pattern, &@block) 461: else 462: new_path = request.params['REQUEST_URI'].gsub(@pattern, @replacement) 463: end 464: response.socket.write(Mongrel::Const::REDIRECT % new_path) 465: end 466: end
