I have reviewed the many questions posted here related to .htaccess
, apache
, mod-rewrite
and regex
, but I\'m just not get
I don't know if RewriteMap work with .htaccess
files, but anyway here's my solution for virtual host, which should work flawlessly.
Create a RewriteMap file. See here for more information. This is a very simple text file with: first, the wrong URL without the '/', then one space (at least) and then the right url, like this:
one-piece-episode-528 /watch-anime/o/one-piece/one-piece-episode-528.html
dexter-season-6-episode-1 /watch-interesting-stuff/d/dexter/dexter-season-6-episode-1.html
breaking-bad-full-season-3 /watch-interesting-stuff/b/breaking-bad/breaking-bad-full-season-3.html
and so on.
convert this simple text file into hash map. For example:
httxt2dbm -i mapanime.txt -o mapanime.map
Now declare it in your vhost:
RewriteMap mapanime \
dbm:/pathtofile/mapanime.map
So all in all your vhost should look like:
<VirtualHost *>
RewriteEngine On
RewriteMap mapanime \
dbm:/pathtofile/mapanime.map
# don't touch the URL, but try to search if it exists in mapanime
RewriteRule /([^/]*)/$ - [QSA,NC,E=VARANIME:${mapanime:$1|notfound}]
# if VARANIME not empty *and*
# VARANIME different from "notfound":
RewriteCond %{ENV:VARANIME} ^(notfound|)$
# then redirect it to the right URL:
# QSA = query string append
# R = redirect, 301 = definitive redirect
# L = last = don't go further
RewriteRule . %{ENV:VARANIME} [QSA,R=301,L]
</VirtualHost>
Hope this helps.
I don't see a simpler solution, but I'm pretty sure this one will work.
If it doesn't work: read my usual "two hints", and add the rewrite log in your question.
Please try to use the RewriteLog
directive: it helps you to track down such problems:
# Trace:
# (!) file gets big quickly, remove in prod environments:
RewriteLog "/web/logs/mywebsite.rewrite.log"
RewriteLogLevel 9
RewriteEngine On
My favorite tool to check for regexp:
