Redirecton with iframe

please help me code :)

[friendabc]

Hi, experts,

I have a subdomain , say sub.mydomain.com
I would like to put in this an index.html or index.php to redirect it to another url, say mydomain2.com/somefolders/. What I want is to keep the old subdomain name appearing in browser. I heard that I can use a iframe. Could you help me with the code?
Thank you in advance

it will better serve you to actually learn how to do this yourself. it is very easy just search for "iframe" in the search engines and you will find many tutorials

if you don't want to learn, you can just paste this code into your site
<IFRAME SRC="http://www.webmasterworld.com" TITLE="titlegoeshere" WIDTH="100%" HEIGHT="100%">
