relative href to another page not working with AngularJS

I have the following code:

<a href='/abc'>abc</a>

when I click it it redirects me to

localhost:4444/abc

and the page looks broken, i.e. the AngularJS code does not work, but there is no error from the AngularJS side.

While going to

localhost:4444/abc

through the address bar works fine. Any ideas?
