I have three files on web server "SERVER1" - main.htm, top.htm anf page1.asp main.htm --------- <html> <frameset rows="100,100"> <frame name="top" src="top.htm"> <frame name="bottom" src="http://URLofSERVER2/bottom.htm" > </frameset> </html> top.htm --------- <html> <body> <a href="page1.asp" target="center">Page1</a> <form name="topform" action="http://URLofSERVER2/page2.asp" target="center"> ... </form> </body> </html> I also have two files on web server "SERVER2" (its URL is completely different from SERVER1's URL) - bottom.htm and page2.asp bottom.htm ----------- <html> <frameset cols="100,100%,100"> <frame name="left" src="left.htm"> <frame name="center" src="center.htm"> <frame name="right" src="right.htm"> </frameset> </html> When I click on link "Page1" or submit form "topform" in top.htm, new browser window is opened, but I want that "page1.asp" and "page2.asp" are showed in frame named "center". How can I do it?
