Method Detail

percentEscape

public static void percentEscape(StringBuilder buf,
                                 String value)

Does a simple %-escaping of the UTF-8 bytes of the value. Keep only some know safe characters.

Parameters:

buf - the buffer to which escaped chars are appended

value - the value to escape

encodeContentDisposition

public static String encodeContentDisposition(String filename,
                                              boolean inline,
                                              String userAgent)

Encodes a Content-Disposition header. For some user agents the full RFC-2231 encoding won't be performed as they don't understand it.

Parameters:

filename - the filename

inline - true for an inline disposition, false for an attachment

userAgent - the userAgent

Returns:

a full string to set as value of a Content-Disposition header
