Is CEF cache persistent between sessions ?

[aligre]

Hello

My configuration :
CEF version : 114
Os version : windows 10
The CEF cache path is set and always same.

Some tests I've made seem to show that queries are found in the cach if they comes from the same CefClient.
Then two different CefClients, in the same session or from two successive sessions, don't share queries responses.

This is also what I understand from the comments about cef_settings_t.cache_path :

HTML5 databases such as localStorage will only persist across sessions if a cache path is specified

Am I right, the queries responses are not persistenly cached ?
I hope I'm wrong ...

Regards,
Julien

A single cache directory can only be used by a single main process. Do not use the same cache directory for multiple processes at the same time.

To add a little, if you enforce a single instance of the main CEF process running at a time (only one "app" with its browser, renderer, plugin, ... processes) then yes, the cache is persistent as long as you keep using the same cache folder. Local storage works properly too.

If you need to run multiple "apps" (multiple main browser processes) then you must give each one its own cache folder, and so changes one makes to its cache folder will not apply to any other cache folder.

Hello

thanks both of you for the answsers.
Yes, we use a different cache directories for each main browser processes.

I thinks I've found the cause of non-cached responses in our scenario, it's because the server add the following header that I didnt know

vary: Accept-Encoding,Origin,Referer

and the requests doesnt have the same Referer in their headers

I was surprised by what I saw in fiddler and naively I thaught there was an issue in CEF cache management.
Thanks to your answers, I've focused on the queries content and found the right cause.

Thanks
