How to flush cache?

When to flush cache?

Why do we flush cache?

Chuck Tomasi · ‎10-25-2016

You can flush the cache by typing cache.do in the navigation for filter.

When? When things don't seem to be going right and you can verify you did everything right. Avoid doing this in production instances as it may impact performance as people rebuild items in the cache.

Why? Because many things like form layout are held in a cache for faster performance and it needs to be purged periodically.

Flush the SN cache memory just like you do for your browser.

When you face issue with the UI display.taking too much time to load or if you have done some changes but it is not reflecting in your form.

In jelly, We used g1/j1 tags which save the UI display in cache memory to better the performances. So to remove those cache we do it..

Please refer section 2.3 in below wiki link for more details.

Hello Chuck,

Do you know if a cache flush is necessary if a change is in made in the html section of a widget?

Thanks,

Chad

My understanding is "no", you don't need to mess with the cache when doing widget development.

Silly (maybe) question. Does cache.do flush all nodes, or just the one you are connected to when you run it.
