title: ETag for GET in angular js - do i need to check on server-side
body: <p>I'm trying to implement etag for a GET request in angular JS, So far I've seen <a href="https://github.com/forforf/angular-etag" rel="nofollow">https://github.com/forforf/angular-etag</a> 
  <a href="https://www.npmjs.com/package/angular-http-etag" rel="nofollow">https://www.npmjs.com/package/angular-http-etag</a>
  and restangular(a complicated one but good). They all say it gives build in support for GET request, which i think means i don't have to code anything on server side(which is in c#.NET).</p>
  
  <p>Am i right in assuming that, OR i've to use CacheCow or something to look for ETAG in the header and send 304 response.</p>
  
  <p>Just a background, I've to use ETAG instead of cache(angular), so as to get latest data from server.</p>
