favicon.ico doesn't appear when I deploy application to google app engine
===

I have placed favicon.ico in the web-pages  directory of my project. I also placed a tag in the jsp page to put the favicon on the browser :

    <link rel="icon" type="image/ico" href="./favicon.ico"/>

but still the favicon doesn't appear in the browser.

Why is that ? What do I need to do put the favicon in the browser.
