clear web app caching

#1 · August 12, 2019, 1:14 pm

Hello,

I would like to create a web app, with the possibility to make updates online (adding data). I do updates myself for my client. But it seems necessary that the client clear the cache on his browser for each new update.
Is there a way, in the web app to make the caching clear automaticaly without the client be obliged to do it himself ?

Regards,
Denis

@cdy44-2 take a look here:

Normally pressing Shift-F5 on the web browser while viewing the application should be enough to reload all content.

THank you for your answer. I knew that (Shift-F5), but I was hoping it was possible to achieve this task by lines of code....

It's possible but with server side scripting only (take a look at the link above).
A trick I usually do is adding a false random URL parameter:

https://myappdomain.com?falseparameter=23461234

This will force the browser to reload the content.

How do you use your trick with false domain ?

What's a false domain?
In any case just add ?parametername=value to the URL
An be sure the value is different each time.
