oh!!! so, could i use a simplistic logic like :
replace latest '#' from string with '?xrdcl.unzip='
ALICE stores files in the form of GUID (that last uid)
and when i request access to a lfn i get the guid and the authz envelope
for accessing the file ... so, it is guaranteed that i will always get a
url with a GUID ...
Given this, do you thing that i could use the logic from above?

that would be great! if it is possible it would be best if
the same format of '#file' is recognized (as this is the url that i get
when requesting lfn access)
Thanks a lot!!
