LTM Web Acceleration Profile Configuration
My organization and I are new to BIG-IP. Everything has been working quite well, but I do have a question about Web Acceleration profiles. For LTM, the iApps I have used so far create one by default. This seemed to be working satisfactorily, until the programmers began complaining about it. The previous load balancer my company used apparently did not do anything like F5's Web Acceleration profiles do, so the old ADC wasn't caching any items in that regard. I got with the programmers and told them we can clear the cache when we make changes, we can reduce the maximum age, and we can limit what items are cached, but they don't like that either. They want the LTM to recognize a document has changed without any cache clearing or anything like that. They want to be able to make changes to web pages (including to items the Web Acceleration profiles caches) and have all machines see those changes instantly and automatically. Of course, this obviously needs to happen, and the web pages we serve up change often, but the only way I see of doing that is clearing the cache on the Web Acceleration profile. Is there a provision for the LTM to check the web server for items to get their last modified dates so that if an item is changed the new version will be served up automagically instead of the old version? Do Web Acceleration profiles provide enough improvement to justify their use in a medium sized environment? What do other companies regularly do?
