I'm working on a site that is hosted on a server running IIS, I don't have access to the IIS admin. I'm keen to implement custom error pages, but I also want to ensure they return the appropriate server header code. I've attempted to implement this by inserting the following code (for a 404 for example) in the page (asp): <% Response.status = "404 Not Found" %> My problem is this: when I check the custom page with online server header checker tools some return the correct code and some return a 403 forbidden error. Is that a problem with the tools? For example, http://www.seoconsultants.com/tools/headers.asp works but http://tools.seobook.com/server-header-checker/# doesn't ???
