+Subject: [PATCH] [uri] Retain original encodings for path, query, and fragment
+ fields
+
+iPXE decodes any percent-encoded characters during the URI parsing
+stage, thereby allowing protocol implementations to consume the raw
+field values directly without further decoding.
+
+When reconstructing a URI string for use in an HTTP request line, the
+percent-encoding is currently reapplied in a reversible way: we
+guarantee that our reconstructed URI string could be decoded to give
+the same raw field values.
+
+This technically violates RFC3986, which states that "URIs that differ
+in the replacement of a reserved character with its corresponding
+percent-encoded octet are not equivalent". Experiments show that
+several HTTP server applications will attach meaning to the choice of
+whether or not a particular character was percent-encoded, even when
+the percent-encoding is unnecessary from the perspective of parsing
+the URI into its component fields.
+
+Fix by storing the originally encoded substrings for the path, query,
+and fragment fields and using these original encoded versions when
+reconstructing a URI string. The path field is also stored as a
+decoded string, for use by protocols such as TFTP that communicate
+using raw strings rather than URI-encoded strings. All other fields
+(such as the username and password) continue to be stored only in
+their decoded versions since nothing ever needs to know the originally
+encoded versions of these fields.
