See Also
"Page Redirection - JavaScript" for more techniques of redirecting from one page to another.

This Active Server Page demonstrates a good method for redirecting your visitor to a different page.

Before any <html> tag we simply identify the target page and then call "Response.Redirect" to change to the requested page. For most browsers that is all that is required.

Save Source
Right mouse button here and select "save target as" to save the source. Note that you will be download a "txt" file which must be renamed.

Some older browsers do not correctly handle server requested redirection. As a result we follow the "Response.Redirect" with our standard redirection JavaScript. See our "Page Redirection - JavaScript" for an explanation of the JavaScript.

Obviously before using these functions you would want to remove the verbose comments.

See this script in action.

DIM sTarget

sTarget = "../../javascripts/examples/redirectiontarget.htm"
Response.Redirect sTarget

'   You might ask, why should we have anything else?
'
'   Some browsers (especially older browsers) do not
'   correctly handle the server requesting the browser
'   to redirect to another page.
'
'   As a result we include our standard redirection
'   javascript page.  The only difference is that we
'   use the ASP variable substitution to provide the
'   redirection target.
'
'   Browsers that correctly handle server directed
'   redirection will never see the html that follows
'   in this file.
