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!
安裝方式
- Upload the
if-modified-sincefolder to the/wp-content/plugins/directory - Activate the plugin through the ‘Plugins’ menu in WordPress
- No need to configure, it just works!
常見問題集
- Do I need this when I already use a caching plugin like W3 Total Cache?
-
Some plugins like W3TC support the If-Modified-Since header, so there’s no need to install this plugin.
- How do I know if the plugin works after installing?
-
You can test If Modified Since here

This plugin caused our site to show blank pages often. The site would initially work, then after a reload it was completely blank. No errors or anything. The theme files failed to load, just completely blank.
After investigation it turned out to be this plugin. Possibly broken due to be being so old.
This description should scare you off anyway which I should guess what was happening to normal users:
“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”
