Example 1 with HeaderElement

the class AbstractRequest method executeUrl.

/**
     * Executes the given <code>url</code> with the given <code>httpMethod</code>. In the case of httpMethods that do
     * not support automatic redirection, manually handle the HTTP temporary redirect (307) and retry with the new URL.
     * 
     * @param httpMethod
     *            the HTTP method to use
     * @param url
     *            the url to execute (in milliseconds)
     * @param contentString
     *            the content to be sent to the given <code>url</code> or <code>null</code> if no content should be
     *            sent.
     * @param contentType
     *            the content type of the given <code>contentString</code>
     * @return the response body or <code>NULL</code> when the request went wrong
