Part
String
. If the Part did not include a header
of the specified name, this method returns null
.
If there are multiple headers with the same name, this method
returns the first header in the part.
The header name is case insensitive. You can use
this method with any request header.getHeader

header nameString
containing the
value of the requested
header, or null

Some servlet containers do not allow
servlets to access headers using this method, in
which case this method returns null

This method is not guaranteed to succeed if called more than once for the same part. This allows a particular implementation to use, for example, file renaming, where possible, rather than copying all of the underlying data, thus gaining a significant performance benefit.
