## com.google.appengine.api.urlfetch
Class FetchOptions

    java.lang.Object
      com.google.appengine.api.urlfetch.FetchOptions

All Implemented Interfaces:
  java.io.Serializable

    public final class FetchOptions

extends java.lang.Object
implements java.io.Serializable

Allows users to customize the behavior of `URLFetchService` operations.

If `allowTruncate` is called, `URLFetchService` will truncate large responses and return them without error.

If (@link #disallowTruncate} is called, `ResponseTooLargeException` will be thrown if the response is too large.

If `followRedirects` is called the `URLFetchService` operation will follow redirects.

If `doNotFollowRedirects()` is called the `URLFetchService` operation will not follow redirects.

Notes on usage:
The recommended way to instantiate a `FetchOptions` object is to statically import `FetchOptions.Builder`.* and invoke a static creation method followed by an instance mutator (if needed):

>      import static com.google.appengine.api.urlfetch.FetchOptions.Builder.*;

>      ...
>      URL url = getURLToFetch();
>      urlFetchService.fetch(new HTTPRequest(url, HTTPMethod.GET,
>          allowTruncate()));

>      urlFetchService.fetch(new HTTPRequest(url, HTTPMethod.GET,
>          allowTruncate().doNotFollowRedirects()));
