We've been working with our store and look up in cache use and wondering about its effect on system resources. The topic is pretty well summed up by the following question. So far I haven't found any documented explanation of how it's implemented.
"I would be curious to see how Layer7 physically stores the data. Are they writing to a database table or storing local files or saving in RAM? Does it allocate the entire spot for a large file + many sessions, or dynamically assign based on actual use? Those may help determine best practices for enabling cache assertions. "
