All of our Skuid pages are housed within full-screen Visualforce pages. We’ve been experimenting with cache=“true” and expires=x (where x is the time until the page expires) in the Visualforce pages so as to cache repetitive information, like the nav bar, logo, page structure, etc. Some of our Skuid pages are quite meaty, so this can have a dramatically positive effect, for example reducing the load time for one commonly used page from 5sec to 1sec for every repeat load. But it’s raised some questions:
- If we set the expiry time to a high value (say several hours), we’ve run into issues where the popup message to login again appears. Can’t quite understand this. Our session timeout in Salesforce is set to 12 hours and the expiry was set to 8 hours in one test and we were repeatedly seeing the popup. I can test more thoroughly, but I wondered initially on what basis that popup appears.
