Remove someone else's website URL (which contains forward slashes) via .htaccess on WordPress -

i've searched high , low solution , i've tried has failed. looking through our server logs , noticed number of 404s url has had variable added end of (for reasons we're still trying understand).

a url should read:

www.example.com/property1/property2/

instead reads:

www.example.com/property1/property2/http:/www.anothersite.com/ (notice single slash after 'http:')

i tried using both:

rewriterule ^/http:/www.anothersite.com/(.*)$ /$1 [l,qsa] , rewriterule ^/http:/$ /but no avail. added complication site wordpress, i've been placing new code on line after rewritebase / of code (standard wp):

# begin wordpress  <ifmodule mod_rewrite.c> rewriteengine on rewritebase /  rewriterule ^index\.php$ - [l] rewritecond %{request_filename} !-f rewritecond %{request_filename} !-d rewriterule . /index.php [l] </ifmodule>  # end wordpress 

any assistance appreciated! :)

use following rewrite rule

rewriterule ^(.*)/http:.*$ $1 [l,nc,qsa,r=301] 

assuming want www.example.com/property1/property2/http:/www.anothersite.com/ redirected www.example.com/property1/property2. use following end url /

rewriterule ^(.*/)http:.*$ $1 [l,nc,qsa,r=301]
