Link from subdomain to domain

[Zenigata]

Hi,
how can I link a page in subdomain.domain.tld to a page in domain.tld? If I use an absolute link, it points to the root of the subdomain.

Note I don't want to link with http:// and I use Apache

Please help me, thanks.

why not use an absolute [......] link?

Hi,
I don't want to use http:// because this generate a new connection request to my server and I think it will overload it (I'm on a shared hosting and my site has a lot of visitors).

Is there a different way to link to domain without using [,...] maybe with a php function or .htaccess?

Thanks

i'm sorry but i don't see how making an absolute href will iniate a new connection request as oppposed to using a relative href.
