I work with multiple sites without cache warmup technology. So I created one.
Don’t be mislead, it’s simple.
<br /> $ ./warmup.rb www.someurl.tld<br />
- download http://www.someurl.tld/sitemap.xml
- parse that sitemap for urls
- run through that list of urls, downloading every HTML to warmup the cache
