So the objects are of unknowable length. Possibly infinite.
In store.log -1 means unknown/undefined. It is only a display value.
Which is correct, advertised size (Content-Length) was not provided.

That would be the Content-Length header. Which you say the server is not
providing. Nothing anyone but the server admin can do about that.
When the Content-Length is not known that documented calculation is not
possible. Squid does cache objects with unspecified length unless there
is some _other_ reason not to.
