Refresh page cache if website has changed

metalbote commented 6 years ago

I have following problem, with settings ttl =600 i want to cache pages, so that if user has no internet connection, he will see the cached version. But if he has connection, and something changed on website the cache should be refreshed.

In the current situation, it shows the cached version although website has already changed. If I try to reload, nothing changes, it still shows the cached version.

With a separate app.cacheclear Button as reload, it works, but after press the app crashes.

Hello,

app.clearcache() is the way to go. Your app should not crash ... can you tell me is this is on iOS and Android and the name of your app so that I can try mayself.

It is the android version. In the current version available in play store i did not implement the app.clearcache button because it crashed.

As i said my main problem is that the app does not refresh the updated content on the website, although you drag down and trigger the normal refresh. It is weird because on some tested smartphone it does update and on others not, no matter which android version

I rebuild a new version which does not interfer with the current deployed:

There is only one Screen with TTL = 120 and it does not automatically updates pages when the get updated in the web, also after 2 minutes or longer. Reload dragging does reloading from cache.

If TTL = -1 (Cache Disabled) the pages are updated, but only after a complete close.
Last modified metatag in page header seems to have no effect.
A static entry-page, which is embedded and therefore to be updated pages are not in first place has no effect
Button with app.reload in Topbar has some weird effects. Pressing it reloads the page but from cache, and Topbar Icons disappear
Button with app.reload in page has same effects
Button with app.cacheclear in Topbar seems to have no effect in first place, but it behaves like no cache set. If the app is completely closed afterwards, the pages get updated.
Button with app.cacheclear in page acts the same way With app.cacheclear something changed since i opened this thread, it does not crash the app anymore, but misbehavior in updating pages is still a problem for my customers. At minimum there should be a function similar to strg-f5 in browsers to force a reload.

Hello,

Sorry for the late response, I will look into this.

Is it possible to give me one URL for testing ? I could use your app but I guess that if you point me to one URL I would be more efficient.

For my own tests i created a completely indepent instance at http://www.kfd-koeln.de/app/, for testing purposes use http://www.kfd-koeln.de/app/aktuelles. In this website i embedded the reload buttons and a phpdate function for testing. The delivered app uses http://www.kfd-koeln.de/appdata/.

Thank for your response
