.htaccess redirect from GET variable to url string

Question

I need to redirect

/search?keywords=somesearchterm

to

/search/somesearchterm

This seems incredibly basic but I've been pounding my head against it for an hour.

Thanks for taking the time to look at this.

Answer 1

You want to implement what is called a "301 Redirect" with mod_rewrite.

RewriteEngine ON
RewriteRule ^/search\?keywords=somesearchterm$ /search/somesearchterm

adding regular expressions:

RewriteEngine ON
RewriteRule ^/search\?keywords=(.+) /search/$1 [R=301,L]

R=301 means provide a 301 Header redirect so the user's URL changes in the browser, and L means don't process any more rewrite rules if this one matches.

---

If you want to do the reverse -- in other words, if someone goes to mysite.com/search/asearchterm and you want the URL to stay the same, but "behind the scenes" you want it to load a certain server script, do this:

RewriteEngine ON
RewriteRule ^/search/(.+) /search.php\?keywords=$1 [L]

Answer 2

You can not match aginst Query string in RewriteRule directive. Use %{THE_REQUEST} or %{QUERY_STRING} server variables to match the Query string :

The following rule works fine for this redirection

 RewriteEngine On
 RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s/search\?kewords=([^&\s]+) [NC]
 RewriteRule ^ /search/%1? [NE,NC,R,L]

RewriteRule ^search/([^/]+)/?$ /search?keyword=$1 [QSA,NC,L]
