If Modified Since

Screenshots

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. If you have any issues using If Modified Since, find a bug or have an idea to make the plugin even better then please help to improve If Modified Since. If you don’t report it, I can’t fix it!
