Does someone know a field change log method/class for the client, agents and the web?

Hello,

Currently I am working on a basic template for our application development like superNTF on OpenNTF.org.

SuperNTF has a fine document change log for the Client and backend functions / agents but not for the Web.

Does anyone know an alternative, which works for the client, backend agents and the web? I want to log changes to the document directly…

I thought there was one, but I could not find it.

Thanks in advance
