Internet Host Name

i'm writing a prog in which i assume
that a name of all the internet servers
is build like that:
http://name1.name2.name3
example:
http://www.google.com
so i would like to know it right

if not then if i have a request from the broweser how can i get the host name from it

example:
GET http://www.google.com/home_pg.gif HTTP 1.0

the host name is www.google.com

thanks

In general, you can not assume that all server names consist of only three parts. Although most of them do, there also a lot of servers with 2,4,5... parts in their name.

I didn't really understand your question, could you define it a bit better?

proskig

I agree with tosse, e.g. some have .co.uk instead of .com

jkr

But you can assume that the host name is enclosed between '//' and the next '/'...

i would like to know
how can i get the host name from the broweser request

when broweser requests a file the request look like:

GET http://www.goole.com/home_page.gif HTTP 1.0 header...

i need to get the host name from these request <or any other request like it>

can i do what jkr said
i mean is the host name is writen between // and / <every host name>

my goal is to write a func that will get the host name from the request
<it shouldn't depend on the host name niether on the request what i mean is it should work for every request the broweser might send>
