Use .htaaccess and mod_rewrite to handle sub-domains effectively.

I am running couple of sub-domains via our main domain: http://www.techarena.in

Sub-domains in use:
http://forums.techarena.in
http://gallery.techarena.in

Here are the contents of my current .htaacess file:

RewriteEngine on
RewriteCond %{HTTP_HOST} ^207\.58\.143\.178$
RewriteRule ^/?(.*)$ http://www.techarena.in/$1 [R=301,L,NS]

ErrorDocument 400 /
ErrorDocument 401 /
ErrorDocument 403 /
ErrorDocument 404 /
ErrorDocument 500 /

RewriteCond %{HTTP_HOST} ^techarena\.in
RewriteRule ^(.*)$ http://www.techarena.in/$1 [R=permanent,L]

Code (markup):

I am re-directing all the traffic from our Domain IP to domain via above code, and also re-directing all the 404 and/or error pages to main URL:

Problem 1 - check this url, entire CSS is misplaced.
http://www.techarena.in/adsd/inde
How do i fix this problem ?

Problem 2 - Crawlers are re-directing content from foll. dirs as well:
www.techarena.in/forums/
www.techarena.in/gallery/
I want to prohibit this using 301 re-directs (please note, there is lot of content already indexed using the above URLs)
I want to re-direct all the traffic coming from www.techarena.in/forums/ to http://forums.techarena.in
and re-direct all the traffic coming from www.techarena.in/gallery/ to http://gallery.techarena.in

so any user going to this thread:
http://www.techarena.in/forums/showthread.php?t=346155 should be automatically re-directed to http://forums.techarena.in/showthread.php?t=346155

Problem 3:
check the following URL:
http://forums.techarena.in/ads/sdsdd
How badly the same gets displayed (because of unknown image paths and .css file not found) how to manage the same as well ?


Question 1
Should i do some modifications for .htaacess files in my subdomain DIRs as well ? those are currently blank.

Thanks in Advance.

sorry to bump back the thread again, accidentally created 2 topics
I am still waiting for an effective solution.

 

For #1 and 3, you have to change the image paths and .css code as if the new URL is the actual URL. The browsers don't know there fake URLs. I'm a css n00bie.

For #2

Options +Indexes
Options +FollowSymlinks
RewriteEngine on
RewriteRule ^gallery/([^.]+)$ http://gallery.techarena.in/$1/ [R=301,L]
RewriteRule ^forums/([^.]+)$ http://forums.techarena.in/$1/ [R=301,L]
RewriteCond %{HTTP_HOST} ^207\.58\.143\.178$
RewriteRule ^/?(.*)$ http://www.techarena.in/$1 [R=301,L,NS]

ErrorDocument 401 /

ErrorDocument 404 /
ErrorDocument 500 /

RewriteCond %{HTTP_HOST} ^techarena\.in
RewriteRule ^(.*)$ http://www.techarena.in/$1 [R=permanent,L]

 

the above .htaacess is not working
this are the content of my .htacess in root folder /

You can get rid of the

/forums/.htaccess

file.

Is

http://www.techarena.in/.htaccess

where the code's at?? It looks like the

ErrorDocument 404

has it, like that URL doesn't exist.

Do any sites link to your IP address? If not,

RewriteCond %{HTTP_HOST} ^207\.58\.143\.178$
RewriteRule ^([^.]+)$ http://www.techarena.in/$1 [R=301,L,NS]

should be taken out.

What is

RewriteCond %{HTTP_HOST} ^techarena\.in
RewriteRule ^(.*)$ http://www.techarena.in/$1 [R=permanent,L]

for?


http://www.techarena.in/.htaccess

ErrorDocument 400 /
ErrorDocument 401 /
ErrorDocument 403 /
ErrorDocument 404 /
ErrorDocument 500 /
Options +Indexes
Options +FollowSymlinks
RewriteEngine on
RewriteBase /
RewriteRule ^gallery/([^.]+)$ http://gallery.techarena.in/$1 [R=301,L]
RewriteRule ^forums/([^.]+)$ http://forums.techarena.in/$1 [R=301,L]

if you can have the RewriteCond stuff out of there.

And it was missing the

RewriteBase /

code.

 

Thanks for helping out till here:
this is my current .htaacess file

ErrorDocument 400 /
ErrorDocument 401 /
ErrorDocument 403 /
ErrorDocument 404 /
#
Options +Indexes +FollowSymlinks
RewriteEngine on
RewriteBase /
#
# Prevent duplicate content on gallery and forums subdomain
RewriteCond %{HTTP_HOST} ^(gallery¦forums)\.techarena.in
RewriteRule ^(gallery¦forums)/[^.]+$ - [F]
#
# Redirect gallery and forums subdirectories to subdomains
RewriteCond %{HTTP_HOST} ^www\.techarena\.in
RewriteRule ^gallery/([^.]+)$ http://gallery.techarena.in/$1/ [R=301,L]
RewriteCond %{HTTP_HOST} ^www\.techarena\.in
RewriteRule ^forums/([^.]+)$ http://forums.techarena.in/$1/ [R=301,L]
#
RewriteCond %{HTTP_HOST} ^207\.58\.143\.178 [OR]
RewriteCond %{HTTP_HOST} ^techarena\.in
RewriteRule (.*) http://www.techarena.in/$1 [R=permanent,L]

Code (markup):

Replacing the same with the last provided by you, still wont make any effect.

Lot of site content is indexed in google via the IP Adress, hence need to convert any request coming from SERPs via IP to the correct URL.

since site should be indexed via techarena.in I have added additional .htaacess codes to get it re-directed to www.techarena.in

I tried deleting .htacess files from /forums /gallery folder as well.
