Title: If Modified Since Author: ezraverheijen Published: 17 augusti 2015 Last modified: 17 augusti 2015 --- Sök tillägg Det här tillägget **har inte testats med någon av de 3 senaste huvudversionerna av WordPress**. Det kanske inte längre underhålls och kan ha kompatibilitetsproblem när det används tillsammans med nyare versioner av WordPress. ![](https://s.w.org/plugins/geopattern-icon/if-modified-since.svg) # If Modified Since Av [ezraverheijen](https://profiles.wordpress.org/ezraverheijen/) [Ladda ner](https://downloads.wordpress.org/plugin/if-modified-since.0.9.zip) * [Detaljer](https://sv.wordpress.org/plugins/if-modified-since/#description) * [Recensioner](https://sv.wordpress.org/plugins/if-modified-since/#reviews) * [Installation](https://sv.wordpress.org/plugins/if-modified-since/#installation) * [Utveckling](https://sv.wordpress.org/plugins/if-modified-since/#developers) [Support](https://wordpress.org/support/plugin/if-modified-since/) ## Beskrivning 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](https://github.com/ezraverheijen/wp-if-modified-since). If you don’t report it, I can’t fix it! ## Installation 1. Upload the `if-modified-since` folder to the `/wp-content/plugins/` directory 2. Activate the plugin through the ’Plugins’ menu in WordPress 3. No need to configure, it just works! ## Vanliga frågor 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?

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" ![](https://secure.gravatar.com/avatar/5c9f90d4afcd330f8e303dae3d483865c423b4731de5e880e198cabc91464850? s=60&d=retro&r=g) ### 󠀁[Deserves a 5 star](https://wordpress.org/support/topic/deserves-a-5-star/)󠁿 [Jayanta](https://profiles.wordpress.org/jkmwp/) 3 september 2016 Yes, it works. thanks a lot, man. I have been trying to fix it for 3 hours now and your plugin has made it look so easy. ![](https://secure.gravatar.com/avatar/e2cd8591ee5454dbadd17260dfb625e47675057ef435bf32698de5a75112d12a? s=60&d=retro&r=g) ### 󠀁[Great!](https://wordpress.org/support/topic/great-4580/)󠁿 [klinsky](https://profiles.wordpress.org/klinsky/) 3 september 2016 Simple and elegant script code.
