subdomains and search engines

[flycast]

Hello...
I have a domain say [example.com....]
I want to add subdomains for testing my customers sites, say that is [customer.example.com....] Now when sombody hits [customer.example.com...] the paged serverd comes from a folder in domain's root folder called "customer".

I do not want Google or anybody else to index or browse any of those subdomains. I have excluded the directory "customer" in the robots.txt file. Is there anything else I can do or should be doing to avoid the se's from indexing the subdomains?

To block a sub domain with robots.txt you must place the file inside the root of the sub domain, not in the top level root.

Example:

You must put the robots.txt file inside the "customer" sub folder. Not the master directory.

Place this in each sub domain directory you do NOT want indexed.

Thanks. That's so logical, why didn't I think of that! I appreciate your help.
