How can I change present directory to another particulary from server1 to server 2

i want to activate an html file located at server2 while an html which will activate it is located at server1.. how can i do it?

 

Sorry, I'm not following you. What do you mean by "activate"? (If you are wanting to do what I think you're wanting to do, you'll have to rely on Ajax for cross-site scripting, but that brings a CRAPLOAD of security risks into the equation.)

 

what i only wanted is to change the default directory that's all thank you

 

Try a redirect from "server1" to "server2". There are several forms of redirects available. Since you are using a HTML file, you can try a meta refresh on the old file which you want to redirect users to the new file.
<meta http-equiv="refresh" content="2;url=http://[your new HTML file]">
