the above code doesn't work. possible using if else in htaccess check types of urls , rewrite accordingly?

edit:

rewritecond %{http_host} !^www\.(.+)$ [nc] rewritecond %{http_host} (.+)\.learntipsandtricks\.com [nc] rewritecond %{request_uri} ^/p-(\d+)-(\d+)$ [nc] rewriterule ^(.*)$ http://learntipsandtricks.com/blog/%1/[first part of sub-domain]/%2/$1 [p] 

how can first part of sub-domain here.

thank you.

http_host doesn't include url-path. if want match against url-path, use request_uri instead

rewritecond %{request_uri} ^/p-(\d+)-(\d+)$ 

for example.

from rewritecond directive

• rewritecond backreferences: these backreferences of form %n (0 <= n <= 9). %1 %9 provide access grouped parts (again, in parentheses) of pattern, from last matched rewritecond in current set of conditions. %0 provides access whole string matched pattern.

therefore, if want capture both domain , url-path components, must combine http_host , request_uri in 1 rewritecond

rewritecond %{http_host} !^www\.(.+)$ [nc] rewritecond %{http_host} (.+)\.learntipsandtricks\.com [nc] rewritecond %{http_host}%{request_uri} ^(.+)\.learntipsandtricks\.com/p-(\d+)-(\d+)$ [nc] rewriterule ^(.*)$ http://learntipsandtricks.com/blog/%2/%1/%3/$1 [p]
