Class LaxRedirectStrategy

java.lang.Object

org.apache.hc.client5.http.impl.DefaultRedirectStrategy

org.apache.hc.client5.http.impl.LaxRedirectStrategy

All Implemented Interfaces:

RedirectStrategy

@Contract(threading=STATELESS)
public class LaxRedirectStrategy
extends DefaultRedirectStrategy

A lax implementation of the RedirectStrategy that automatically handles HTTP redirects for HEAD, GET, POST, and DELETE requests based on the response status code.

This strategy relaxes the HTTP specification restrictions on automatic redirection of POST requests, allowing redirects for these methods where the specification might otherwise prohibit them. This can be useful in scenarios where a server indicates a redirect for a POST request that the client should follow.

This class is thread-safe and stateless, suitable for use across multiple threads without additional synchronization.

5.4

isRedirected

public boolean isRedirected(org.apache.hc.core5.http.HttpRequest request,
 org.apache.hc.core5.http.HttpResponse response,
 org.apache.hc.core5.http.protocol.HttpContext context)

Description copied from interface: RedirectStrategy

Determines if a request should be redirected to a new location given the response from the target server.

isRedirected in interface RedirectStrategy

Overrides:

isRedirected in class DefaultRedirectStrategy

Parameters:

request - the executed request

response - the response received from the target server

context - the context for the request execution

Returns:

true if the request should be redirected, false otherwise

isRedirectAllowed

public boolean isRedirectAllowed(org.apache.hc.core5.http.HttpHost currentTarget,
 org.apache.hc.core5.http.HttpHost newTarget,
 org.apache.hc.core5.http.HttpRequest redirect,
 org.apache.hc.core5.http.protocol.HttpContext context)

Description copied from interface: RedirectStrategy

Determines if the given redirect should be executed or the redirect response should be returned to the caller without further processing.

It is legal for this method implementation to modify the redirect request in order to make it suitable for redirect execution.

Specified by:

isRedirectAllowed in interface RedirectStrategy

Overrides:

isRedirectAllowed in class DefaultRedirectStrategy

isRedirectable

protected boolean isRedirectable(String method)
