===== What is the difference between LiteMage Cache and LSCache? ==== =
LiteMage Cache is the world's fastest full page cache developed specifically for Magento sites. LSCache is a general caching solution for most applications. LSCache works similarly to Apache's mod_cache or Varnish, but is implemented in a more efficient way.
LiteMage Cache is an improved version of LSCache which works together with the LiteMage Cache extension for Magento to deliver superior caching with an ESI implementation geared specifically for Magento pages.
===== Can I use LiteMage with LSWS version 4.x.x? ==== =
No. Only LSWS versions 5.0 and later have ESI support.
Have a look at our page about enabling this feature.
Yes, you can. And doing so is highly recommended, especially on production servers. For instructions on how to enable this, have a look at our page about this feature.
Navigate to the Magento Admin Panel ⇒ Cache Management screen. Go to “Flush LiteMage Cache By IDs”, select the “CMS Page IDs” drop down, and put the 404 page ID in the input box. After that, click the “Flush LiteMage Cache By IDs” button. For most sites, that ID is 1. However, to be sure, this can be checked by going to Magento Admin Panel → CMS → Pages and find the page for “404 Not Found”. Then click to go to the Edit screen. The URL will then show something similar to “…/cms_page/edit/page_id/1/key/…” with the page ID for this one being “1”. As of version 1.3.4, the 404 pages caused by disabled product or category will carry related product/category IDs. So when the product/category is enabled, the related 404 pages will then be automatically purged as well.
404 pages are cached with the same public TTL as regular pages are.
