  - extractTokenFromHeader
```
@Deprecated
static String extractTokenFromHeader(String header,
                                                 String key)
```
    Deprecated.
    
    Extracts a token from a header that has a given key. For instance if the header is
    content-type=multipart/form-data boundary=myboundary and the key is boundary the myboundary will be returned.
    
    Parameters:
    
    header - The header
    
    key - The key that identifies the token to extract
    
    Returns:
    
    The token, or null if it was not found
  - extractQuotedValueFromHeader
```
static String extractQuotedValueFromHeader(String header,
                                           String key)
```
    Extracts a quoted value from a header that has a given key. For instance if the header is
    content-disposition=form-data; name="my field" and the key is name then "my field" will be returned without the quotes.
    
    Parameters:
    
    header - The header
    
    key - The key that identifies the token to extract
    
    Returns:
    
    The token, or null if it was not found
  - extractQuotedValueFromHeaderWithEncoding
```
static String extractQuotedValueFromHeaderWithEncoding(String header,
                                                       String key)
```
    Extracts a quoted value from a header that has a given key. For instance if the header is
    content-disposition=form-data; filename*="utf-8''test.txt" and the key is filename* then "test.txt" will be returned after extracting character set and language (following RFC 2231) and performing URL decoding to the value using the specified encoding
    
    Parameters:
    
    header - The header
    
    key - The key that identifies the token to extract
    
    Returns:
    
    The token, or null if it was not found
