---++ ObjectMethod *headers* <tt>({...}) -> $headersHashRef</tt>

Gets/Sets all response headers. Keys are headers name and values
are scalars for single-valued headers or arrayref for multivalued ones.



---++ ObjectMethod *getHeader* <tt>([$name]) -> $value</tt>

If called without parameters returns all present header names,
otherwise returns a list (maybe with a single element) of values
associated with $name.



---++ ObjectMethod *deleteHeader* <tt>($h1,$h2,...)</tt>

Deletes headers whose names are passed.



---++ ObjectMethod *pushHeader* <tt>($name,$value)</tt>

Adds $value to list of values associated with header $name.



---++ ObjectMethod *cookies* <tt>([\@cookies]) -> @cookies</tt>
