Default Headers

<p>
	The following annotations are provided for specifying default header values for requests and responses:
</p>
<ul class='javatree'>
	<li class='ja'>
		{@link oajr.annotation.Rest#reqHeaders() Rest(reqHeaders)} 
		<br>Defines default headers on request when the client doesn't specify them.
	<li class='ja'>
		{@link oajr.annotation.Rest#resHeaders() Rest(resHeaders)}
		<br>Appends the specified headers if they weren't already set programmatically.	
</ul>		

<h5 class='figure'>Example:</h5>
<p class='bpcode w800'>
	<jc>// Servlet with default headers</jc>
	<ja>@Rest</ja>(

		<jc>// Assume "text/json" Accept value when Accept not specified</jc>
		reqHeaders={<js>"Accept: text/json"</js>},

		<jc>// Add a version header attribute to all responses</jc>
		resHeaders={<js>"X-Version: 1.0"</js>}
	)
	<jk>public</jk> MyRestServlet <jk>extends</jk> BasicRestServlet {
		...
	}			
</p>
<p>
	Default headers can also be specified programmatically by overriding the following methods:
</p>
<ul class='javatree'>
	<li class='jac'>
		{@link oajr.RestContextBuilder}
		<ul>
			<li class='jm'>
				{@link oajr.RestContextBuilder#reqHeaders(String[])}
			<li class='jm'>
				{@link oajr.RestContextBuilder#resHeaders(String[])}
		</ul>
	</li>
</ul>
