Save WebView on Load of another Activity?

I have a webview and i load it with an external URL so this loads the First page and i click on a link goes to the second page then i click on the third page .

Now on this third page i have written a Javascript to open Another Activity which works fine . But on close of this Activity my WebView reloads the First page again which should had rather been same page where the Activity was called ..??

Any idea as to What is it that i am doing wrong ?

Thanks in Advance.

I think you should in the onCreate() mnethod

that web view already created & displays the web pages.

only you need to check this thats all.
