Limitations
- Parse up to65536 ASCII characters as a media-type token pair and ordered token/quoted-string parameters with escaping; at most100 parameters. Normalize media type/parameter names,retain values and report duplicate values/conflicts (charset compared without case). No charset guessing,payload decoding or RFC2231 extended-parameter decoding.
- Text fields are limited to100,000 UTF16 units each and400,000 combined UTF8 bytes; file fields have their own displayed limits. Combined output is at most4MiB. Processing stops after30 seconds; tool-specific bounds may be tighter.
- Generated source is a downloadable result and is not executed here. Inspection does not establish remote behavior, trust or standards certification.
