LiteSpeed Cache for WordPress: Crawler

The crawler travels through your site, refreshing pages that have expired in the cache. This makes it less likely that your visitors will encounter uncached pages.

The crawler must be enabled at the server level, or it will not work. Please contact your hosting provider, or see our instructions.

Before using any of the functions in this area, please be sure that you have configured the crawler to your liking.

1. If you don't already have a sitemap file, you can generate one here by pressing the Generate Crawler File button. (If you already have an XML sitemap, you can enter the URL on the Crawler settings tab.)
2. Set Activate to Enable to turn on the crawler.
3. If you want to watch the crawler's progress, press the Show Crawler Status button.
4. You can wait for the crawler to begin on its own according to its configuration settings, or you can press the Manually Run button and start it immediately. If the crawler is already running, this button will be ignored.

If you've opted to watch the crawler status, your screen will look something like the image above. The messages in the status window will vary from these, as this screenshot was grabbed from a small installation with few pages to crawl.

Here's an example of a watch screen from a crawler running on a larger site:

And here is an explanation of some of the terms:

• Size: The number of URLs in the sitemap. This example has 181.
• Crawler: Indicates which crawler number you are watching. It's number 1 in this example. There could be multiple crawlers working, depending on your settings.
• Position: The URL number currently being fetched from the sitemap list.
• Threads: Indicates the number of threads currently being used to fetch URLs. There may be multiple threads fetching. It is smart and will adjust based on your load settings.
• Status: Indicates the current crawler status. In this example, Stopped due to reset meta position means that the site purged or the sitemap changed while it was crawling, and as such, the crawler will restart from the top.

If you wish to keep a particular path from being crawled, you may enter it in the Sitemap Generation Blacklist box and press Save. After the crawler has run for the first time, if it encounters any pages marked do-not-cache they will be added to this Blacklist automatically.
