asp_web_howto thread: Response.redirect

Message #1 by "Simon Garstin" <sales@o...> on Sat, 8 Dec 2001 12:27:05 -0000

Hi,



the reason for the recent 404 file question:



suppose a response.redirect command does not work because the web page does

not exist or the destination server is down - is there any way to stay

within the asp page and do something else eg.



<fictitious code>

if not response.redirect "http://www.somesite.com/somepage.htm" then

    <do something else>

end if

</fictitious code>

You will need a component to do a HTTP GET request for the page on the 2nd

server. If the HTTP Response is 200 OK, then you execute the redirect.



If the HTTP response is 404 (File Not Found), or if there is no HTTP

response (the server is not available, or able to respond), then you do

Response.Redirect



Look into using the Microsoft ServerXMLHTTP component to do this for you.



Cheers

Ken

You could even use the filesystemobject (fso) in a

function to see if the file exists.  Just pass the

file name to the function.  If it comes back true, the

page exists.  Something like this:



<%

 If FileExists("gothere.asp") then

   response.redirect

 else

   do something

 end if

%>

Mark,



I tried that but it only works for files on the local server.
