Webmasters Stack Exchange is a question and answer site for pro webmasters. It's 100% free, no registration required.

I would like htaccess to rewrite example.com/something_%26_else into example.com/something_%2526_else.

I'm importing a bunch of pages that have ampersands in the title from Mediawiki. These are encoded as %26. Drupal, for various reasons, has decided double encode the url it to have it become %2526. I simply can't create the alisis within Drupal so I have to use htaccess

This is what I have as my rule so far as RewriteRule ^w/([^%26]+)\%26(.*)$ w/$1\%2526$2 [R=301]

I asked this question three months ago on stackexchange and was not able to get it working. I tried hiring a contractor for this but was unable to find one. So this my last ditch effort before I completely give up. I really appreciate the help.

All the best, Patrick

In all honesty, wouldn't it be better for everyone involved to run an UPDATE query against drupal's database to convert all the %26's back to ampersands, so that Drupal stops double-encoding them? –  DerfK Jan 3 '11 at 16:49
@DerfK That would break links from other sites. Since there's about a 1000 pages with this problem, I would like to avoid this but if I don't find a solution, then that I just have to do it. Thanks –  Patrick Jan 3 '11 at 17:02

'noescape|NE' (no URI escaping of output)

This flag prevents mod_rewrite from applying the usual URI escaping rules to the result of a rewrite. Ordinarily, special characters (such as '%', '$', ';', and so on) will be escaped into their hexcode equivalents ('%25', '%24', and '%3B', respectively); this flag prevents this from happening. This allows percent symbols to appear in the output
