Question

I need guideline about using of robots.txt problem is as following.

I have one live website "www.faisal.com" or "faisal.com" and have two testing web servers as follows

"faisal.jupiter.com" and "faisal.dev.com"

I want one robots.txt to handle this all, i don't want crawlers to index pages from "faisal.jupiter.com" and "faisal.dev.com" only allowed to index pages from "www.faisal.com" or "faisal.com"

I want one robots.txt file which will be on all web servers and and should allow indexing only live website.

Answer 1

The disallow commands specifies only relative URL so I guess you cannot have the same robots.txt file for all.

Why not force HTTP authentification on the dev/test servers ?

That way the robots wont be able to crawl these servers.

Seems like a good idea if you want to allow specific people to check them but not everybody trying to find flaws in your not yet debugged new version ...

Especially now that you gave the adresses to everybody on the web.
