can you have 2 robots.txt files on site?

one in main and one in subdomain

[stiksandstones]

I have an estore located at my site
www.mysite.com
and my store is on a subdomain
[store.mysite.com...]

I was looking at logs (disregard dates, its the same no matter the date) and saw this;;

I have my robots.txt file in main root of my site. I was checking my logs and find it says
66.249.64.52 - - [01/Aug/2005:23:17:00 -0400] "GET /robots.txt HTTP/1.0" 200 632 "-" "Googlebot/2.1 (+http://www.google.com/bot.html)"
66.249.64.52 - - [01/Aug/2005:23:17:00 -0400] "GET / HTTP/1.0" 200 6397 "-" "Googlebot/2.1 (+http://www.google.com/bot.html)"

I know the 200 code means it was a success
but nothing more, isnt it supposed to crawl ALL my pages? looks like it didnt crawl any.

So then I checked my logs for my subdomain (store.mysite.com) and found...

66.249.64.16 - - [28/Mar/2005:21:38:50 -0800] "GET /robots.txt HTTP/1.0" 404 - "-" "Googlebot/2.1 (+http://www.google.com/bot.html)"
66.249.64.16 - - [28/Mar/2005:21:38:57 -0800] "GET / HTTP/1.0" 200 14980 "-" "Googlebot/2.1 (+http://www.google.com/bot.html)"

404 means error, didnt find the robots.txt in my [store.mysite.com...] Am I supposed to have a robots in my subdomain AND my main domain?

You certainly need a robots.txt file for any (sub-)domain where you want robots to obey it.

[Jioffri]

But shouldn't the robots.txt in the root take precedence over the entire domain as long as all subdomains are based on the same TLD domain name? For example, if the website is [anywebsite.com...] and the estore subdomain is [estore.anywebsite.com?...]

I'm thinking that you should have a robots.txt file in the root of your subdomain. But... not knowing your configuration all I can offer is an easy way to answer your question.

Go to [store.mysite.com...] ... if not found then the answer would be yes... you need a separate file.

No - one robots.txt per unique domain name (including subdomains), per protocol and per port.

Maj,

OK, thanks for clarifying that. However, should I ask my hosting service to add and edit the robots.txt file for me since I do not have one on my webstore which is a subdomain of my tld? Or is there another way to add one or perhaps resource(s) you can refer me to that will explain how to do this?

I put a robots in my main root
and in my subdomain...

What is the risk I run of having 2 now?

[Lord Majestic]

There is no risk.
