I would like someone to have a look at the following URL: http://www.holidaylettings.co.uk/rentals/mijas-costa/22122 And explain to my how I can achieve the following: If you enter the above URL into your browser and remove any character or several characters from either the word rentals or the word mijas-costa and hit the enter/return key the URL above automatically jumps back to the original one. Example: http://www.holidaylettings.co.uk/reals/mijas-costa/22122 (couple of letter taken out of the word rentals) http://www.holidaylettings.co.uk/rentals/mijsta/22122 (couple letters taken out of mijas-costa) but after hitting the enter key on keyboard Both incorrect urls jump back to the original; http://www.holidaylettings.co.uk/rentals/mijas-costa/22122 I presume this is done with mod rewrite and .htaccess I would be very grateful if someone could please tell me how?
