Hi,

I currently have the use case that I would like to add do additional
changes when a POST is sent to Sling. One example is to set a last
modified date on a node when something is changed/updated in the
repository.
While this can be done through observation using observation is not
optimal especially as the user context is lost.
One idea I had is to add kind of a post processor to the sling post
servlet which is invoked after all changes are done and before the
session is safed. The problem here is now that the post processor should
know what has been done in order to do the right thing.
Fortunately, the sling post servlet uses the html response to keep track
of all changes. Unfortunately this is remembered in a string buffer
which is not suitable for further processing.
So what about keeping track of the changes in the html response in a way
that it makes possible for the post processor to inspect what has changed?
This once was the case, but since this functionality was private and not
really used, I converted the modification list to a StringBuffer. This
may of course be reverted ...
In addition, if we add post-processing, we should probably also add
pre-processing for symmetry, right ? But how ?

Felix
