- Why am I getting (304) Not Modified error on some links when using . . .
Any ideas why on some links that I try to access using HttpWebRequest I am getting "The remote server returned an error: (304) Not Modified " in the code? The code I'm using is from Jeff's post here (the page seems to have disappeared, see an archive copy at the Wayback Machine)
- How does 304 Not Modified work exactly? - Stack Overflow
The browser then sends a request with the If-Modified-Since or If-None-Match header, telling the server to send a 304 if the content still has that date or ETag The server needs some way of calculating a date-modified or ETag for each version of each resource; this typically comes from the filesystem or a separate database column

- 304 Not Modified with 200 (from cache) - Stack Overflow
The 304 response status code is the servers' way of letting the browser know that the response hasn't changed and is still valid If the browser receives a 304 response, it can "freshen" the relevant stale response(s) And subsequent requests to the resource can again be served from the browser cache without checking with the remote server
