Re: [users@httpd] Deny,Allow confusion

Hello, Maxim,

###
1. Order Deny,Allow
2. Deny from all
3. Allow from dev.example.com
###

This actually says:
1. By default allow access to everyone (because it's deny, allow)
2. Now deny from everyone.
3. Now allow only to dev.example.com.

So at the end, only users from dev.example.com will receive access to
the path, correct ?


I think so.

If so, why use deny then allow, wouldn't this produce the same result?
###
1. Order Allow,Deny
2. Allow from dev.example.com
###


In this case, yes. I think it is same.

And at general, do I always need use deny & allow, or can I just use
one of them (like deny) because Apache by default allows access to
everyone, isn't this the case?


I think if one is enough, why two. It depends what you want to do. Also as you know already, the directive Order might change the default.

also, for this, are the two similar?


I don't think they are same.

###
<Directory /docroot>
Order Deny,Allow
Deny from all
Allow from env=let_me_in
</Directory>
###


This only allows "env=let_me_in", because Allow is evaluated after Deny.

###
<Directory /docroot>
Order Allow,Deny
Allow from env=let_me_in
Deny from all
</Directory>
###


This will deny all hosts, because "Deny from all" will overwrite the Allow directive.

Thank you very much.


You are welcome.
