I have a system where it was loading a fontface from my own server. I replaced this font for the google's webfont version (droid sans). In order to accomplish this, I removed all the declarations that were calling this font on my server, then I added the following line on each file that were using the font:
<link href='//fonts.googleapis.com/css?family=Droid+Sans:400,700' rel='stylesheet' type='text/css'/>
Ok, great! now I'm loading the font from google's repository. Nice!
The Problem:
Now, in some pages where I had only one request for the droid sans font on my server, the font located on google's repository is being called twice or three times, depending on the page. At first I thought it could be because the browser was downloading some of the variations of the font, depending on the page.. but I'm not confortable with this explanation because I believe should download everything just once. I really didn't want these unnecessary requests..
That said, I'd like your help to know if there's a way I could do to make sure it will be loaded once and that's it! Also help clearing to me why I'm getting this behavior.
