one Rewrite is messing up another?

[halfasleeps]

ok I have this rewrite rule:
rewritecond %{http_host} ^kranichs.com [nc]
rewriterule ^(.*)$ http://www.kranichs.com/$1 [r=301,nc]

which inforces always having http://www always prefiex my domain...it always has worked and still does.



I now added this:
RewriteRule ^.*_(\d+)c\.htm(&.*)? /K_category.php?cid=$1$2

which makes something like this:
http://www.kranichs.com/Simon_G_53c.htm
give you this page:
http://www.kranichs.com/K_category.php?cid=53

which works but if you dont type in the www. part and try to access it like this: http://kranichs.com/Simon_G_53c.htm it still takes you to the right page but it the URL actually changes to http://www.kranichs.com/K_category.php?cid=53 which I dont want the user to see this I want the user to always see the prettier URL.

I know this is caused because of the other rule that enforces the www. but I dont know how to fix this?

I hope this makes sense.

Can anyone help?

THANKS!

Both rules run in the same request. The www is added, the URL is changed to /K_category.php?cid=53, and then the visible redirect happens.

You need the L flag to stop processing when the rule has matched.
You should do the redirect first.

Code: Select all

Options +FollowSymLinks

RewriteEngine On

RewriteCond %{HTTP_HOST} ^(kranichs\.com)$ [NC]
RewriteRule ^(.*)$ http://www.%1/$1 [R=301,L]

RewriteRule ^.*_(\d+)c\.htm(&.*)?$ /K_category.php?cid=$1$2 [QSA,L]

Now, the www is added and the visible redirect happens. Then the URL is changed to /K_category.php?cid=53 without the user knowing.

Thank you very much!!!! I simply added a [L] flag to each rule and it worked.

I think I understand that by putting the [L] it broke the operation in 2 to requests instead of one. The redirection happened in the first request and then the rewrite happend after the redirection in the second request. ....but I am still confused as to why it wasnt working in the first place when it was all being done in the same request. If someone wouldnt mind explaining this a little deeper I think it could help prevent me from running into this often in the future.

THANKS!

I am very new to apache/mod_rewrite/and regex. (I do know some OOP languages tho) Anyways I am trying to learn, I just read the book Apahe mod_rewrite by Rich Bowen which helped a lot.

The redirection has to happen at the very end (it starts a new request), so if you have

Code: Select all

rewritecond %{http_host} ^kranichs.com [nc]
rewriterule ^(.*)$ http://www.kranichs.com/$1 [r=301,nc]

RewriteRule ^.*_(\d+)c\.htm(&.*)? /K_category.php?cid=$1$2

it knows it has to add www, but it doesn't redirect yet. Then the second rule changes the URL and finally the redirect happens.
