Cache Batch Update

The cache batch update feature enables you to pre-load files from a specified web site or perform an up-to-date check on documents already in the cache. This is typically initiated when the load on the Proxy Server is at its lowest. From the Cache Batch Updates form you can create, edit, and delete batches of URLs and enable and disable batch updating.

You can actively cache content (as opposed to on-demand), by specifying files to be batch updated. The Proxy Server enables you to perform an up-to-date check on several files currently in the cache, or pre-load multiple files in a particular web site.

At larger sites with a network of servers and proxies, administrators might want to use batch updating to pre-load a given area of the web. The batch process would perform a recursive descent across links in the document and cache the content locally. This function can be a burden on remote servers, so be careful when using it. Measures are taken to keep the process from performing recursion indefinitely, and the parameters in the bu.conf configuration file provides some control of this process.

Use the Proxy Server access logs to determine which sites are the most commonly active and perform a batch update on those sites to increase performance.
