[Solved] Disable trailing dot in domaine name?

Hello,
I'm testing during few hours to block trailing dot in my lighttp configuration, unfortunately, I can't

samples of this problem :

If I try to check the dot in the $_SERVER["REQUEST_URI"] with PHP, it don't found it and begin the $_SERVER["REQUEST_URI"] with "/" only.

I think it can generate duplicate content for the search engines.
Thanks for your help.

You don't, and please don't try. The dot is perfectly valid.

You don't think it's a bad think (about duplicate content) ?

No I don't. Same like upper/lower case hostnames. They are just "the same".

Thank you for your help Stbuehler.
