Strange thing

Hi,

I have a strange problem (for me ). A website under ox server X.4.11
works fine local and external with IE, but whit firefox he is very slow
on local or externals connections. And when i'm on the local lan i type
http://xxx.yyy.zzz:16080/esacv2/ it works fine ...
The 16080 appears in the virtual host.conf but i didn't use virtuals
host ...

Any idea

Best regards
