Hide php file extention

how and why?

[nfs2]

I noticed on most sites, there are no file extentions. Just urls like mydomain.com/action?something&result=this and there is no file extention

An example of this is digg.com. I know its a php site but theres no file extention to be found. At first i was thinking they used mod_rewrite to get rid of the file extention, but i dont think that anymore.

Does anyone know how?

hi nfs2

I think that this can be done using Apache's mod rewrite module along with .htaccess, you can try searching on the web for .htaccess abilities and documentation or better yet ask in the Apache forum right here in webmasterworld/forum92

It is likely Content Negotiation. The W3 released a new article this week on Content Negotiation -- a good read:
