ErrorDocument 404 redirect PLEASE HELP (blocked robots.txt)

Hello,

To keep the visitors on the page i created .httaccess and placed

ErrorDocument 404 redirect http://www.yoursite-name.com/sitemap.php

It works fine!
when i type www.yoursite-name.com/blanlabakhdfd

it goest to http://www.yoursite-name.com/sitemap.php

I am fine with that. Unfortunately, my IT guy, the company where i work, blocked robots.txt file, he said robots.txt file is not necessary for SEO purposes. he also said that SEearch engine robots will index the site with out it. and added by having robots.txt and accidently put the wrong information in there, you could have serious problems. I told him that you need to put the correct info in there.

anyways, what happens now when robots.txt is blocked

when i type www.yoursite-name.com/robotx.txt in browse

it goest to http://www.yoursite-name.com/sitemap.php

the question is this:

Will this CONFUSE the SE robots (spiders)? Will my site still be indexed? Any sugesstions? comments?

 

Until you change the error page in your .htaccess to a relative path, you will not generate a 404 for the robots.txt, but a 302. A 302 is a temporary redirect, and Google will index the resulting content from the redirect under the url it comes in on.
