Hi,
I would prefer if this issue could be fixed within QGIS Server. I also
have the same problem when copying projects.
We could combine this effort with a more persistent project/layer cache
of QGIS server, so the cache would survive Apache restarts.
I would be available for co-financing if others would join the effort.

Hey Burghardt,
As a workaround for now it's pretty easy to read the xml file and
replace the layer ids using Python. QGIS doesn't care about the
format of the id as long as it's a strings so you could replace them
all with a GUID if you wanted.

Dear list,
I enjoy working with templates for QGIS projects. This brings when
working with QGIS Desktop many advantages, but leads to problems
with the QGIS Web Client. When I save a project file under a
different name, the id of the layer, unfortunately, is maintained.
If I use both project files in the qgis-server, this creates
problems with caching of layer. That is particularly evident when
identical layer named differently or otherwise be symbolized.
This topic is discussed on several occasions in the past [1,2] and
has been referred to as "bug" or "limitation". In [2] it's said
that the combination of project name and layer ID could be a
solution for the problem. Up to and including version 2.8.1, the
change has not yet been carried out. Is there an effort to change
the creation of the layer ID in a future release?
Kind regards
Burghardt
