Hello, I have build a new site but on each image I get something like  '/Grand_Combin_N.jpg?ver=gQW_EBljfV5hnrKFFcMNyQ%3d%3d'. How do I turn this off?

I'm not sure that you can turn it of - there may be a web config setting.

I suggest that you don't. The purpose of this is to allow long duration image caching at the browser improving performance, and reducing load on your server and infrastructure. Instead add the web config entries needed for the long duration cache headers and see your web site speed up.

Richard, I know how to cache and I also know it does not depend on 'versioning as parameter'. I will do a compare with other sites that do not have this behavior

The setting 'AddCachebusterToResourceUris' was missing from dbo.PortalSettings. Adding this and setting it to false changed the behavior.

INSERT INTO [dbo].[PortalSettings] ([PortalID], [SettingName], [SettingValue], [CreatedByUserID], [CreatedOnDate], [LastModifiedByUserID], [LastModifiedOnDate], [IsSecure])
VALUES (0, 'AddCachebusterToResourceUris','false', -1, GETDATE(), -1, GETDATE(), 0);

Hi Mariette,

Sorry if I was teaching you kids stuff.

May I ask why you want to remove it? ISTM that it's crucial for allowing cache busting to work properly.

Security reasons

Fair enough.

I'm curious because I don't know what any security exposure could be, but I guess security reasons always trumps everything else.

Whoa... I didn't realize how far back this setting goes.  :)

It seems it is default behavior in a new 9.11.1 install to not add that setting to PortalSettings. I tried adding it also to HostSettings assuming it would act global but that did not work, so each new portal needs this added.

A global setting might be a good idea to start an issue/discussion to get added.  🤔
