The spec still only mentions application/x-www-form-urlencoded, so multipart/form-data parsing is up to the application (or, more practically, a library used by the application). > It should mean that the getParameterMap() method, for instance, has at > least to "peek" at the body, determine if it /could/ contain parameters, > and if yes parse it to extract them.

You're confusing POST data (in general) with POST data identified as parsable by the servlet spec in section 3.1.1 (of 2.5... not sure about 3.0). Tomcat will simply ignore multipart/form-data requests when it comes to parameter parsing. Other libraries can be rigged to provide parameter data from both sources (GET and multipart POST). - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAko/3ZsACgkQ9CaO5/Lv0PDyiACgknhVNvhfRj2aUvPLct31BlW6 r4kAn0QKoKlmm4ouQ13Fy9Sq1yhdz7Am =VIgv -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
