How to know which Apache version your host is using?

[moroose]

Hi
Hope someone can tell me how to tell which Apache version my host is using.
I need the info to debug a problem with my deny to all,except my ip

I used this:

<Limit GET POST>
order deny,allow
deny from all
allow from ***.***.**.*
</Limit>

But it denies me access as well

then used this:

RewriteEngine on
RewriteCond %{REMOTE_ADDR}!^***\.***\.**\.**$
RewriteRule .? - [F]

still my ip is denied access,too

Appreciate any help i can get

usually you can see that in the response headers.
for example the WebmasterWorld site returns the following header among others:

Server: Apache/2.0.52
