Hello,

on my page I show images in a lightbox. My task is now to make these lightbox galleries accessable via direct links like http://www.domain1.com/show-gallery/title-of-gallery/12345 or if they come from an external page like Google (if visitors find a gallery in google's search result). I only have to rewrite the link above and redirect them to portals homepage (because with javascript I'm able to get the title (title-of-gallery) and the id (12345) from url of the gallery and then I'will open the lightbox).

I tried with the following condition (?!http://(.*)?(domain1|domain2|domain2|domain2)).* (the rule (RewriteRule ^/(show-gallery)/(\d+)?(\/)?([^\/]*)?(\/)?(\d+)? / [I,L]) itself works properly) but it sometimes redirect to / if I only want to open gallery lightbox on the page itself.

# redirect to portals homepage if referer is different than one of my domains.
RewriteCond Referer: (?!http://(.*)?(domain1|domain2)).*
RewriteRule ^/(show-gallery)/(\d+)?(\/)?([^\/]*)?(\/)?(\d+)? / [I,L]

Rewriting should work as follows:
a) Direct access via http://www.domain1.com/show-gallery/title-of-gallery/12345 should redirect to http://www.domain1.com/
b) From Google's search result user should be redirected to http://www.domain1.com
c) If user clicks on a gallery if he is on my page (http://www.domain1.com or http://www.domain2.com) the lightbox should open without any redirect.

Best regards,
Roland

Please try to fix the rules like this:

RewriteCond Referer: (?!.*(?:domain1|domain2).*).*
RewriteRule /show-gallery/[^/]+/\d+ http\://www.domain1.com/ [I,RP]

Hi Anton,

I tried your version of these rules, but it does not work if I click the link (http://www.domain1.com/show-gallery/title-of-gallery/12345) from Google's search result.
When page is loaded, document.referrer looks like this: "http://www.google.at/url?sa=t&source=web&ct=res&cd=4&ved=0CBIQFjAD&url=http%3A%2F%2Fwww.domain1.com%2Fshow-gallery%2Ftitle-of-galery%2F12345&rct=j" and it seems that it does not match with (?!.*(?:domain1|domain2).*).*

Do you have any idea?


Kind regards,
Roland

Firstly, please confirm it's ISAPI_Rewrite 2 you are using.

And please try to fix your config like this:

RewriteCond Host: .*(?:domain1|domain2).*
RewriteRule /show-gallery/[^/]+/\d+ http\://www.domain1.com/ [I,RP]

RewriteCond Referer: (?!.*(?:domain1|domain2).*).*
RewriteRule /url\?.*www\.(?:domain1|domain2)\.com/show-gallery/[^/]+/\d+.* http\://www.domain1.com/ [I,RP]
