- * about removing backslash escaping.
- *
- * Now realm parameter is user-defined and human-readable, strange things
- * happen when it contains quotes:
- * - Apache allows quotes in realm, but apparently uses realm value without
- * backslashes for digest computation
- * - Squid allows (manually escaped) quotes there, but it is impossible to
- * authorize with either escaped or unescaped quotes used in digest,
- * probably it can't parse the response (?)
- * - Both IE and Firefox display realm value with backslashes in
- * the password popup and apparently use the same value for digest
- *
- * HTTP_Request2 follows IE and Firefox (and hopefully RFC 2617) in
- * quoted-string handling, unfortunately that means failure to authorize
- * sometimes
