I could go into a longer explanation if you would like, here is the abridged version.
Most of the time, the customer isn?t looking for a solution that caches every last piece of data on their public network. Usually, the goal of the customer is three fold. 1) reduce server load 2) reduce network congestion 3) do 1 & 2 without throwing hardware or more bandwidth at the problem (money). They want to do these three things to enhance user experience providing for longer Web site visits, which can translate into greater advertising and e-commerce revenue, however, those goals usually leave the customer with limited choices.
I address all three of those points with LastCache. When I do, I find the customer is more than satisfied with the service. When we add in a price point where the cost of our caching service is equal to or lower than traditional bandwidth, customers start wondering why Akamai charges so much.
XFR?s LastCache does not cache everything, neither does any other caching solution. We get the big stuff that degrades user experience, sucks bandwidth, and kills servers.
To answer your question, with a little work, we can integrate and cache from most types of dynamically generated pages regardless of how they are compiled (php, asp, etc).
Cache update / refresh data for HTML is placed in html headers and read by the cache servers on initial connection / download. Much like DNS?s updating and propagation. For rich file types, we set updates based on customer preference.
Can I set you up with a trial offering.. I think you will be more than satisfied.
