How to Update CSP Application in a Client Browser
Sometimes you can face the situation when you did update the web app on Caché server but you cannot get the newest version of the app in a browser.
Here are couple recipes which help me to solve it. From simplest to more sophisticated and not obvious.
1. Refresh page in a browser
In Chrome it is Ctrl+R or 'Refresh' button. Obvious, but helpful.
2. Hard reset in a browser
If you are in Chrome, open Developer tools

and then right click on Refresh button. Less obvious and very helpful sometimes.

3. Clear cache in CSP Gateway
If 1 and 2 don't work for you, try to flush the CSP Gateway cache.
Open Caché Management Portal and search for Gateway:

Open CSP Gateway Management page and choose System Status.

Go to cached and clear cached file or clear all the cache - click on the black dot.

Hope that helps!

Additionally in web app settings specify:
- Serve Files: Always
- Serve Files Timeout: 0
Note, that it would disable caching completely.
