Hi,

I already done with my testing on MOD SEO, now i want to redirect all request on my existing site (forum related page) to this new site. i dont want the forum back to main site, i want to keep in sub-domain.

Right now, im redirecting all request from http://www.tamilminnal.net to forum.tamilminnal.net. This actually solve my problem, but i need to explicitly define to only redirect forum related page to this new sub-domain, because later i will use the main site for other purpose.

Eg: Redirect -www.tamilminnal.net/viewtopic.php?blabla to forum.tamilminnal.net/viewtopic.php?blabla - so, once its reach forum.tamilminnal.net with "viewtopic.php?blabla" the htaccess in this sub-domain will handle the URL rewrite.

So, how can i redirect from main domain to sub-domain based on certain page only (viewforum.php, viewtopic.php, member.php, etc) using htaccess? Can some one help me with .htaccess codes for URL re-write?

It mostly depends on how is the sub-domain installed. If it is installed on the same server, you can just keep the old phpBB's .htaccess in the www domain and just tweak the rewriterules to make them still point to the phpBB scripts, but in the new directory.
For example if you had :

Code: Select all

ftpfiles/www/viewtopic.php

and you now have :

Code: Select all

ftpfiles/www/
ftpfiles/forum/viewtopic.php

you would just need to use ./../forum/ as the path to the script in the rewriterules. Note that you could need to use ../forum/ or even the absolute path /home/ftpfiles/forum/ depending on your server settings.
Following this example, if you had :

Code: Select all

RewriteRule ^forum\.html$ /index.php [QSA,L,NC]

you would need to use :

Code: Select all

RewriteRule ^forum\.html$ ./../forum/index.php [QSA,L,NC]

And all this in the .htacess of the main domain, eg in ftpfiles/www/, and you would of course need to implement a regular .htaccess in your sub domain's .htaccess.

If your sub-domain is installed on another server or cannot be reached using a local path, you would need to specify the full url and to add the R=301 flag, eg :

Code: Select all

RewriteRule ^forum\.html$ /index.php [QSA,L,NC]

would then become :

Code: Select all

RewriteRule ^forum\.html$ http://www.example.com/index.php [QSA,L,NC,R=301]

And so on.
The first solution is better because it will always use only one redirection, while the second one could use two, but it's not that much of a big deal either.

Hi,

Thanks for the great info, appreciate it. Just to clarify, my site directory structure as below:

$FTP/www/viewtopic.php - main site (http://www.tamilminnal.net)
$FTP/www/forum/viewtopic/php - new site (but user will access via http://forum.tamilminnal.net)

so, is my rewrite condition should be:

Code: Select all

RewriteRule ^viewtopic\.php?f=$1&t=$2$ /forum/viewtopic.php?f=$1&t=$2 [QSA,L,NC]

Any update on this?

So in $FTP/www/'s.htaccess, yes, you would just need to use

Code: Select all

RewriteRule ^forum\.html$ /forum/index.php [QSA,L,NC]

and so on, and note that this only means to add the forum/ path to the right part (before the script) not to change anything else such as adding the script on the left side like you did (viewtopic).

And in $FTP/www/forum/ you would just have to generate a regular .htaccess meant to be used in the domain's (so here it's the sud domain's) root, $FTP/www/forum/ that is.

Basically, you need the exact same .htaccess in both directories, except that you'll have to add forum/ in front of the rewriterules script names (right part) in the $FTP/www/ one.

Hi,

Based on your sample, the final URL will be -www.tamilminnal.net/forum/xxxxx right?

What i have in mind, based on certain page (viewforum.php, viewtopic.php) - simply change the domain from -www.tamilminnal.net to forum.tamilminnal.net

This mean, if user access -www.tamilminnal.net/viewtopic.php?f=1&t=2 it should become forum.tamilminnal.net/viewtopic.php?f=1&t=2 and finally the .htaccess in sub-domain will re-write again to clean URL.

ho, damned, the zero dupe will not handle this case.

So just use the full redirect way :

Code: Select all

RewriteRule ^forum\.html$ http://www.example.com/index.php [QSA,L,NC,R=301]

will work, and it's the only way to have your url redirected on a per case basis, eg, let you use the main domain for something else.
