Hi, I have a problem with my domain. Ok I have my original site (call it mainsite.co.uk) and a second site (call this secondsite.co.uk). All the files for second site are stored in a subdomain of the mainsite.

When people access the site using a straight forward domain (www.secondsite.co.uk) everything is fine, when they access a folder with a backslash on the end (www.secondsite.co.uk/folder/) again... everything is fine.

BUT when they access a folder without a backslash (www.secondsite.co.uk/folder) then they get redirected to the subdomain www.secondsites.mainsite.co.uk/folder/

This is the subdomain in which the site is stored....

I just can't work out what the problem is? can this be fixed with an htaccess amendment?

Thanks in advance!!
