Do CDNs work with POST operations?
- by iddqd
I'm using a CDN (Level3) for the first time and I'm a bit confused. I'm accessing dynamic URLs such as http://cdn.mysite.com?getItem=1234 that return text data.
Do CDNs work with HTTP POST operations? When i issue a HTTP POST operation, my "real" server receives this request every time, so I'm wondering if the CDN has a problem with POST operations.
If i use HTTP GET it seems to work, i call the URL once (from my application), i can see my server receiving the request. If i call it a second time, the CDN delivers it directly, my server doesn't get anything. However if i open same the link manually from a second browser tab, my server is asked to deliver again, shouldn't it be cached by now?
Many thanks.
