.htaccess Allow All from Specific User Agent

Question

I have a website I am developing that is also going to be pulled into a web app. I have the following code in my .htaccess file to prevent access from ANYONE that is not on my allowed IP:

Order deny,allow
Deny from all
AuthName "Restricted Area - Authorization Required" 
AuthUserFile /home/content/html/.htpasswd 
AuthType Basic
Require valid-user
Allow from 12.34.567.89 
Satisfy Any

QUESTION: I would like to add an Allow from rule that will ALSO allow a specific HTTP user agent access to the site.

I found this code to redirect if not the user agent:

RewriteEngine on
RewriteCond %{HTTP_USER_AGENT} !=myuseragent
RewriteRule ^files/.*$ / [R=302,L]

But I can't seem to figure out how to turn this into an Allow from rule. Help?

UPDATE

I found the code below to block specific user agents... I would instead like to say "if NOT myuseragent, then block."

<IfModule mod_rewrite.c>
SetEnvIfNoCase ^User-Agent$ .*(libwww-perl|aesop_com_spiderman) HTTP_SAFE_BADBOT
Deny from env=HTTP_SAFE_BADBOT
</ifModule>

Answer 1

SetEnvIfNoCase User-Agent .*google.* search_robot
SetEnvIfNoCase User-Agent .*yahoo.* search_robot
SetEnvIfNoCase User-Agent .*bot.* search_robot
SetEnvIfNoCase User-Agent .*ask.* search_robot

Order Deny,Allow
Deny from All
Allow from env=search_robot

Answer 2

I just want to allow ONE SPECIFIC user agent rather than trying to block all

Here's my config to allow only wget:

SetEnvIf User-Agent .*Wget* wget

Order deny,allow
Deny from all
Allow from env=wget

Answer 3

Allow from and Rewrite* are directives from two different Apache's modules.

The first one is mod_authz_host and the other from mod_rewrite.

You can use mod_rewrite to do what you want:

RewriteEngine on
RewriteCond %{HTTP_USER_AGENT} !=myuseragent
RewriteRule .* - [F,L]

If you don't want to use mode_rewrite, with Apache 2.4 you can use something similar to this:

<Location />
                AuthType Basic
                AuthName "Enter Login and Password to Enter"
                AuthUserFile /home/content/html/.htpasswd
                <If "%{HTTP_USER_AGENT} == 'myuseragent'">
                Require all granted
                </If>
                <Else>
                Require valid-user
                Require ip 12.34.567.89
                </Else>
</Location>
