Overview
If Modified Since tells search engine spiders one of two things about a webpage:
- This webpage has not changed, no need to download again.
- This webpage has changed so download again because there is new information.
If the requested page has not been modified since the time specified by a search engine spider, a 304 (not modified) response will be returned without any message-body.
