I need to redirect automatically lots of url like /file%20name/ ore /file name/ to /file+name/ or /file-name/.
How can I do this with .htacess ?
You can use something like this:
RewriteRule file\ name\ http://example.com/file+name [R=301,NC,NE,L]
Edit after comment:
Try this:
RewriteRule ^([^\ ]*)\ (.*)$ $1-$2 [E=rspace:yes,N]
