BUG/MEDIUM: backend: fix URI hash when a query string is present
Commit 98634f0 ("MEDIUM: backend: Enhance hash-type directive with an
algorithm options") cleaned up the hashing code by using a centralized
function. A bug appeared in get_server_uh() which is the URI hashing
function. Prior to the patch, the function would stop hashing on the
question mark, or on the trailing slash of a maximum directory count.
Consecutive to the patch, this last character is included into the
hash computation. This means that :
GET /0
GET /0?
Are not hashed similarly. The following configuration reproduces it :
mode http
balance uri
server s1 0.0.0.0:1234 redir /s1
server s2 0.0.0.0:1234 redir /s2
Many thanks to Vedran Furac for reporting this issue. The fix must
be backported to 1.5.
