rewritemap based redirection

Postby pramodpmenon » Thu Jul 23, 2009 10:11 pm

I am trying a rewritemap for my domain.

We have urls like example.com/web/redirect?location=(parameter)


This url will redirect to the page mentioned in the paramater.The list of allowed domains for the parameter should come from a rewrite map. All other domains values shoud be redirected to error page.


I worked on this rewritemap. But it is not reaching anywehere.
Code: Select all
RewriteMap allowhost txt:/usr/apache2/conf/allowhost.txt


RewriteCond %{QUERY_STRING} ^location=(.*)[NC]


RewriteCond ${allowhost:%{%1}|NOT-FOUND} !NOT-FOUND


RewriteRule ^/web/redirect /error.html [R=301,L]


allowhost.txt File contents
Code: Select all
http://www.domaina.com NOT-FOUND
http://www.domainb.com NOT-FOUND

Try
Code: Select all
Options +FollowSymLinks

RewriteEngine On

RewriteMap allowhost txt:/usr/apache2/conf/allowhost.txt

# Only match the domain part.
RewriteCond %{QUERY_STRING} ^(.*&)?location=(http://[^/&]+) [NC]
# It will return FOUND if it is found.
RewriteCond ${allowhost:%2|NOT-FOUND} !^FOUND$
# If it wasn't found it will be sent to /error.html.
RewriteRule ^/web/redirect$ /error.html [R=301,L]

and
Code: Select all
http://www.domaina.com FOUND
http://www.domainb.com FOUND

Not working

Hi Richard,
Thanks for the reply. Unfortunaltely it is not working.
It is getting redirected for all domains.
I put following:-
RewriteMap allowhost txt:/usr/apache2/conf/allowhost.txt
RewriteCond %{QUERY_STRING} ^(.*&)?location=https?://(.*) [NC]
RewriteCond ${allowhost:%2|NOT-FOUND} !^FOUND$
RewriteRule ^/web/redirect$ /error.html [R=301,L]


I guess the first match itself is not working. I have put loglevel as 9. I see following in rewrite log.

The RewriteLog you posted does not contain any requests for /web/redirect?location=http://www.domaina.com.

Post your whole mod_rewrite.
