Are asp redirects permanent?

[waynekolenchuk]

I need to redirect a windows-hosted domain with permanent (301) redirects so as to preserve most of the link juice.

I would be using asp page-level redirects, as there are only about 50 relevant pages.

Are these as effective as linux-based 301 redirects in conserving link juice?

Yes, they are! You need to do it like this:

<%@ Language=VBScript %>
<%
' Permanent redirection
Response.Status = "301 Moved Permanently"
Response.AddHeader "Location",  "http://www.example.com/"
Response.End
%>

If you use Response.Redirect instead of Response.Status, it won't return a 301 (permanent redirect) header, it will return a 302 (temporary redirect) header instead.

Other permanent redirect methods are PHP, ColdFusion, Perl, and mod_rewrite. JavaScript and meta tag redirects cannot send a 301 status code.

Hope this helps!

Follow up question --- not sure if I understand the entire situation discussed above, but I have a situation where a site that was ASP.net has been replaced with a WordPress site.  I've performed a Open Link analysis and found that most of the old pages, ie

www.i3bus.com/ProductCategorySummary.aspx?ProductCategoryId=63

are returning a HTTP Status = NO DATA ... when followed ends up at the 404 catch-all page.

I'd like to perform 301 redirects and wondering if your solution above applies?

Thanks for any help.
