Implementation report on generic URI syntax

The test page used was <http: www.ics.uci.edu="" ~fielding="" url="" test1.html="">
It has been tested on:

The following features were tested:

Hierarchical URLs
- Implemented in http, file, and ftp URLs on all tested applications
Nonhierarchical URLs
- Implemented in mailto and news URLs on all tested applications
Escaped encoding
- Implemented on all tested applications above
Fragments
- Implemented on all tested applications above
Userinfo
- Implemented on Lynx/2.7.1 and Mozilla/4.03 (did not test others)
Host/port
- Implemented on all tested applications above
Path
- Implemented on all tested applications above
Relative path resolution
- Lynx/2.7.1, MSIE 3.01, NCSA_Mosaic/2.6 all parse normal examples
  within compliance limits. There are still a couple cases where
  Mozilla/4.03 doesn't handle unknown schemes correctly, but people
  at Netscape claim they will fix those as known bugs once the RFC
  is done.
Semicolon within a segment
- Used in ftp and imap URLs (that is, ";" is reserved for those)
  Also used in file URLs on VMS systems, but I don't count that.
Query
- Used in http and wais URLs
Various types of Base URL
- All tested applications support file and http base URLs.
  All except Mozilla/4.03 supported a test of the "fred" URL
  scheme as a test of an unknown scheme.
