Topic: mod_rewrite help

Hi,

Can anybody help me with this please?

Here's what I have in conf file of oldwiki site.

Alias /test1 /var/www/html/test1
Alias /test2 /var/www/html/test2
#Alias /Wiki /var/www/html/mediawiki

RewriteEngine On
RewriteCond %{HTTP_HOST} !newwiki.samplesite.com$ [NC]
RewriteCond %{REQUEST_URI} /Wiki
RewriteRule ^/(.*)$ http://newwiki.samplesite.com/$1 [L,R=301]


----

I am trying to redirect only Alias /Wiki to the newwiki site. But here's the issue now.
http://oldwiki.samplesite.com/Wiki/index.php/Nitro_RC#Setting_up_Nitro_Engine_for_New_Hobbyist
will redirect to -> http://newwiki.samplesite.com/mediawiki/index.php/Main_Page#Setting_up_Nitro_Engine_for_New_Hobbyist

another sample
http://oldwiki.samplesite/Wiki/index.php/How_to_setup_RC_Car
will redirect to ->
http://newwiki.samplesite.com/mediawiki/index.php/Main_Page

It's basically redirecting to Mainpage of the newwiki. Please help

I've tried to work through your example, but it's a bit confusing.

Firstly, you don't say whether oldwiki.samplesite.com and newwiki.samplesite.com are the same host being served through the same Apache. Lets assume they are.

If so, why are you using Alias directives to map to the default htdocs location? They're normally used if you want to reference content from elsewhere on the server filesystem. That said, at some point you were using an alias entry for /Wiki to /mediawiki though it's now commented out, and your mod_rewrite logic doesn't currently redirect to /mediawiki. So either re-enable that alias entry (and maybe consider using AliasMatch instead), or rewrite the URI with mod_rewrite, as well as redirect.

Also, I have encountered problems when using 301 (permanent) redirects rather than 302's (temporary). The problem is browsers (as much as proxies), will cache this result, and not bother contacting the server in the future. This can be a real pain if you make a mistake during testing, or subsequently decide to change the site logic on your server. So I'd recommend using 302 redirects.

I tried the following minor tweaks to your logic on a test instance of Apache, and it seems to work for me:

Hi tangent,

Thanks for the reply. Sorry for not giving enough info - newbie here. They are on a separate server.

Ok, so if the new wiki site is on a different host, then rather than using mod_rewrite logic, why not just use a Redirect from mod_alias, viz:

Hi again!

Thanks! the simple Redirect fixed it.

Cheers!
