Topic: Custom 404

I'm working on a custom 404 which provides suggested links based on the page being sought.

My question is in 2 parts:

1. When I try and set an ASP page to be a custom 404, the html appears as text on the rendered page. Why is this and can I fix this. Is it possible to have an ASP page as a custom 404. Web Server is IIS6. I wanted to suggest links (sourced from a DB) based on the page address causing the 404 <% =( "http://" & Request.ServerVariables("SERVER_NAME") & Request.ServerVariables("URL") )%>.

2. Whilst working around the problem mentioned above, I have made a .htm page the custom 404 and am using it to manually link to the ASP page to list possible suggested links (sourced from a DB) based on the referer <% = request.ServerVariables("HTTP_REFERER") %>. This introduces another click. I have tried used a meta tag refresh and seperately a javascript redirect to get the .htm page to take you to the ASP page, but the referer is not included. Is there a way around this. Will a response.redirect achieve this?

Hope someone can help with either/both problem(s).

Cheers.

Why shouldn't you be able to use an asp page? Simply change the custom error page in IIS. Doing that all the time.

You can use ASP files as 404 pages, you need to select the type as a URL then point it to your 404 ASP page, eg:-

/HTTPerrors/404page.asp

We use one on our main www.webwiz.net site (have a go if you like).

Beceuase we had a big site change recently the 404 ASP page gets the 404 URL and then if the page has moved redirects based on that URL, if it's not a moved page it shows a sheach form.

You could use the same thing to get the URL for your search, the code below is what we use to get the URL that was a 404:-

'Get the 404 page
str404Page = Request.ServerVariables("Query_String")

'Chop out the crap we don't want
str404Page = LCase(Mid(str404Page, InStr(str404Page, ":80/") + 3, Len(str404Page)))
