Bye passing the htaccess authentication according to the query string

[LOSTBOY]

I have added authentication script like below @ my htaccess

 

AuthUserFile /var/www/mydomain.com/.htpasswd
AuthGroupFile /dev/null
AuthName "Authentication required"
AuthType Basic

<Files "*">  
require valid-user 
</Files>

 

Is there is any way to bypass this authentication for a particular url with specific get variables like

http://mydomain.com/index.php?m=file&action=upload

 

 

Please give me your ideas and suggestions ...to solve this..
