STILL WAITING FOR THE REPLY

 

How would I rewrite a sub-domain like this.

I want to redirect secure.nixism.com to my.nixism.com.

How would I do that?

 

First time using mod_rewrite and would really appreciate some help.

I am using:

Options +FollowSymLinks
RewriteEngine on
RewriteRule ^([a-zA-Z0-9_-]+)/([0-9]+)\.html$ searchresult.php?cat_id=$2[L]
RewriteRule ^madeupword/([a-zA-Z0-9_-]+)/([0-9]+)\.html$ article.php?art_id=$2[L]

Code (markup):

This make the links work like this:

[url]http://www.mysite.com/Pasta-articles/24.html[/url]
[url]http://www.mysite.com/madeupword/How-to-pasta/581.html[/url]

Code (markup):

This seems to work fine but the problem is, my url's are generated dynamically and for me to change them to static links there are spaces between the words.
So the static link looks like this:

[url]http://www.mysite.com/Pasta%20articles/24.html[/url]

Code (markup):

Instead of this:

[url]http://www.mysite.com/Pasta-articles/24.html[/url]

Code (markup):

How can I change this code to replace a space(%20) with a dash(-)?

 

The script has to do the change, like a search and replace there. The script makes the links. mod_rewrite only makes the URLs work.

 

Try \- instead of just -

 

Thanks Nintendo and vasyl

Yes I hade to change the link in my site's script. Lucky it's all templates so you only need to change it in a few places. This is how I created the link for one of the pages:

Next I'll try out your query string examples. It's a great tutorial thank you.

What I would really like is a even cleaner url like what WBseo does.:
www.yoursite.com/general-chat/ (category)
and
www.yoursite.com/general-chat/hello-people/(post inside category)

 

I want to transfer from old domain to new domain with 301 redirect but dont know much about .htaccess codes so plz help me and tell me the way and code that i dont lose users and search engine traffic.
I want to transfer many section (folders) and files to new domain but wanna use index and some section (folder) remain active on old domain so plz tell me

1: How to redirect folders and php and html file to new domain ? plz remember that i will upload all files and folders on new domain with same structure, names and extension as on old domain.

2: What code to put in .htaccess to remain active some section folders and files with php and html extension on old domain ?

3: If i have 100+ php and html files in root and wanna 301 redirect all to new domain but remain index file on odl domain with same name and extension and structure then what code to use to redirect all files to new domain but index remain active on old domain ?

 

I have seen it load down a server by as much as 30%, but that was in an extreme (and dumb) case. We (I won't say where) had thousands of rewrite conditions and rules in our .htaccess file. Once we made generalized rules and trimmed the number of rules to a reasonable amount, the server load dropped to nill.

 

Will anyone plz help me ?

 

How would you go about mod_rewriting OUT a directory? Is it possible?

Can I rewrite this with a rule:
mysite.com/SUPER/ROCKIN/COOL/AWESOME/whatever.html

to this:

mysite.com/COOL/AWESOME/whatever.html

(REWRITE OUT THE SUPER AND ROCKIN WITHOUT REMOVING THE DIRECTORIES)

I feel like this is possible, maybe not...I don't know. I would appreciate any help. Also, if this is possible, anyone have the general rules I would write/follow to make this happen.

SOME ADDITIONAL INFO:
ASSUME THAT "ROCKIN" AND "SUPER" ARE DIRECTORIES THAT CANNOT BE MOVED/DLETED/ETC....

 

old-domain.com/.htaccess

Options +Indexes
Options +FollowSymlinks
RewriteEngine on
RewriteBase /mb/
RewriteRule ^(.*)$ http://www.new-domain.com/$1 [R=301,L]

domain.com/.htaccess

Options +FollowSymLinks +Indexes
RewriteEngine on
RewriteBase /
RewriteRule ^COOL/AWESOME/([^.]+)\.html$ SUPER/ROCKIN/COOL/AWESOME/$1.html [L]

 

thta is great, thanks a lot...It's funny, I could not find one thing on the internet that had insturctions or the code written out to follow...I appreciate it, very nice.

 

If you want to redirect them all seperatly, you can do it like this in your old domain's .htaccess file:

redirect 301 /abc.html http://www.newdomain.com/abc.html
redirect 301 /def.html http://www.newdomain.com/def.html
redirect 301 /ghi.html http://www.newdomain.com/ghi.html

Code (markup):

 

First of all, thanks heaps for this tutorial I really appreciate it and it's already helped me lots. If anyone can help me out in writing a rule for this kind of url I'd be very gratefull.

 

What do you want the URL to look like?
