I'm trying to use one of the RSS feeds from chat.stackexchange.com in my application. I'm using the python feedparser package for this. Feedparser supports a couple of different "conditional get" mechanisms, namely ETag and Last-Modified headers.
However, it doesn't seem like the RSS feed I'm grabbing has these headers. My goal is to reduce the load on the SE servers, so I'd like to find some way of doing a low-bandwidth poll/refresh of the RSS feed.
This is my first time working with RSS feeds at this level, so it's possible that there's an alternate mechanism supported by these feeds that I can use. If someone knows what that mechanism is (or if none exists) I'd appreciate the info.
