+ *
+ * Revision 1.1 2002/01/17 20:53:46 jongfoster
+ * Moving all our URL and URL pattern parsing code to the same file - it
+ * was scattered around in filters.c, loaders.c and parsers.c.
+ *
+ * Providing a single, simple url_match(pattern,url) function - rather than
+ * the 3-line match routine which was repeated all over the place.
+ *
+ * Renaming free_url to free_url_spec, since it frees a struct url_spec.
+ *
+ * Providing parse_http_url() so that URLs can be parsed without faking a
+ * HTTP request line for parse_http_request() or repeating the parsing
+ * code (both of which were techniques that were actually in use).
+ *
+ * Standardizing that struct http_request is used to represent a URL, and
+ * struct url_spec is used to represent a URL pattern. (Before, URLs were
+ * represented as seperate variables and a partially-filled-in url_spec).
+ *
