Overview: Assembly rules
The BIG-IP device manages content in the form of compiled responses in cache, which contain applets that the BIG-IP device uses to assemble pages. The BIG-IP device determines how to assemble content by using the following assessments from assembly rules.
- Which content assembly features to apply, such as Intelligent Browser Referencing and MultiConnect.
- How to change parameter values for embedded URLs by substituting values from the request, or by randomly generated values.
Because the BIG-IP device performs content assembly after it matches the response to a node, it always uses the matched response node's assembly rules, which it caches as part of the original compiled response. If the response matches to a different node than the request, the BIG-IP device considers the assembly rules associated with the request's node as irrelevant.
Management of content served from origin web servers
The primary purpose of the Enable Content Assembly on Proxies setting is to allow the BIG-IP device to compress content as required, and to manage content using the Intelligent Browser Referencing feature, even if the content is not served from cache. Using content compression or Intelligent Browser Referencing, without selecting the Enable Content Assembly on Proxies check box, applies compression to HTML documents and Intelligent Browser Referencing to links in HTML documents that are served from cache, but not to any HTML documents that bypass the cache.
