A cache warmer

Read the blog post on this cache warmer for fuller details.

Instructions for distribution and use

The program is compiled as a single jar file with no dependencies, just 19kb of size. It is located in the target folder.

Properties files:

These two property files, visible here on Github should be located in the same folder as the CacheWarmer-1.0.jar file

• cache-warmer.properties

  • the user agent to simulate a visit by a mobile phone
  • the user agent to simulate a visit by a desktop browser
  • number-of-pages-visited-concurrently-in-one-batch=10
  • page-loading-timeout-in-milliseconds=5000
  • interval-between-two-batches-in-milliseconds=1000
  • interval-between-two-cache-warmup-in-minutes=30

• site-map-urls.txt

  • This file contains one or several urls of the sitemaps that will be visited by the cache warmer.

The warmer will visit the urls listed in two xml tags:

• <loc>https://www.example.fr</loc>
• <image:loc>https://www.example.fr/img/4.jpg</image:loc>

Log files

While running, the cache warmer logs data in two files:

• error-log.txt
• info-log.txt

If you want to create a Java runtime, so that users don't have to install it

jlink --module-path target --add-modules jcachewarmer --output out

For the user

Run: nohup java --module-path . --module jcachewarmer/net.clementlevallois.cachewarmer.controller.Controller &

That's it. The program will read the properties in the two property files and do its thing. It will not stop, runs for ever.
