I want to make a separate domain for images

问题:

I want to set up a domain called img.mydomain.com. It will be a virtual domain that just like my actual domain except for one difference: it will only serve files that end in .jpg .jpeg .gif .png etc. This way I can refer to img.mydomain.com/some_image.jpg. it will speed up the page speed by making the browser think that it's two separate domains (google page speed analyzer is always nagging me to do this).

I'm running apache on a linux server. Should I do this in httpd.conf? If so, what is my first step?

回答1:

create 2 folder for each domains (for example):

• /var/www/domain.com
• /var/www/img.domain.com/

here's what you can put in your httpd.conf

<VirtualHost *:80>   DocumentRoot "/var/www/domain.com"   ServerName domain.com   ServerAlias domain.com www.domain.com   <Directory "/var/www/domain.com">     allow from all     Options +Indexes   </Directory> </VirtualHost>  <VirtualHost *:80>   DocumentRoot "/var/www/img.domain.com/"   ServerName img.domain.com   ServerAlias img.domain.com   <Directory "/var/www/img.domain.com/">     allow from all     Options +Indexes   </Directory> </VirtualHost>
