SiteMap page will act as 404 error page conditionally

[subho]

Hi All
My client wants his website's "sitemap" page will act as 404 error page conditionally.What he means to say is there will be a single page which is "sitemap.php", top of the page custom 404 message will be hidden. When required the page will be displayed as error page otherwise it will act as simple sitemap page with hidden 404 msg.

How to do it with php/javascript? Any suggestion or example would be appriciable.

Thanks in advance-

Just redirect the 404 error to the sitemap page using the web server. If it is apache... you can redirect in the httpd.conf file. If IIS, I think there is a dialog box that lets you enter the page, sitemap.html.

Either way, you need access to the web server. I have never tried a Javascript solution. You could capture the 404 response and redirect in javascript, that should work.
