"max... | Specifies a minimum and a maximum time interval for how long idle state, i.e., state which
was not updated, will be retained.
State will never be cleared until it was idle for less than the minimum time and will never
be kept if it was idle for more than the maximum time.
<p>When new data arrives for previously cleaned-up state, the new data will be handled as if it
was the first data. This can result in previous results being overwritten.
<p>Set to 0 (zero) to never clean-up the state.
<p>NOTE: Cleaning up state requires additional bookkeeping which becomes less expensive for
larger differences of minTime and maxTime. The difference between minTime and maxTime must be
at least 5 minutes.
@param minTime The minimum time interval for which idle state is retained. Set to 0 (zero) to
never clean-up the state.
@param maxTime The maximum time interval for which idle state is retained. Must be at least
5 minutes greater than minTime. Set to 0 (zero) to never clean-up the state. | [

... | Specifies the headers to be exposed to calling clients.
During a simple CORS request, only certain response headers are made available by the
browser, for example using:
<pre>
xhr.getResponseHeader(HttpHeaderNames.CONTENT_TYPE);
</pre>
The headers that are available by default are:
<ul>
<li>Cache-Control</li>
<li>Content-Language</li>
<li>Content-Type</li>
<li>Expires</li>
<li>Last-Modified</li>
<li>Pragma</li>
</ul>
To expose other headers they need to be specified which is what this method enables by
adding the headers to the CORS 'Access-Control-Expose-Headers' response header.
@param headers the values to be added to the 'Access-Control-Expose-Headers' response header
@return {@link CorsConfigBuilder} to support method chaining. | [
