A router test against a test upstream that records each request: an
IPv6 source host written with and without a port, through a /v1/image/
URL with a signature and through an encrypted URL. A public address must
be fetched, a private one refused with 403 without reaching the
upstream. The cases without a port fail: each answers 500.
Model: opus-5-5
The generator page passed the source host and path into the encrypted
URL as entered, so a host spelled in another letter case, or a source
with no path against the same source with /, made separate cache keys
and fetched one upstream image twice. The page now lower-cases the
source host, as /v1/image/ does, and writes an empty source path as /,
before it builds the encrypted URL. The checks the page gained for
#288 still hold.
Model: opus-5-5
The source URL was built by joining the decoded path and query as
text, so a space in the query reached the upstream raw and failed with
502, 100%25.png made a URL Go could not parse and answered 401, and
%20 and %2520 fetched the same path under different cache keys. The
source URL is now built with net/url, so each decoded path and query is
one upstream request matching its signature and cache key; the query
encodes the characters a browser encodes, ' included. The generator page
compares what pixa would fetch with the URL as entered, and answers 400
with the URL to use when they differ, or for a user name and password
or a .. segment.
