我遇到了下面的異常 RedirectException: Maximum redirects (50) exceeded using HttpClient 4.3 on solaris10.

下面是我的代碼
RequestConfig configIdentified = RequestConfig.custom()
.setSocketTimeout(12000).setConnectTimeout(12000)
.setConnectionRequestTimeout(12000)
.setStaleConnectionCheckEnabled(true)
.setCircularRedirectsAllowed(true).build();

136 HttpGet httpget1 = new HttpGet("www.aaa.bbb.com/abc/cde"

;
137 HttpGet httpget2 = new HttpGet(this.getDetailPathUrl(pagenum));
138 try
139 {
140 httpget1.setConfig(configIdentified);
141 httpclient.execute(httpget1, responseHandler);

我想知道如何避免 RedirectException: Maximum redirects (50) exceeded

先謝謝大家。

非常感謝 bikong0411 的指點(diǎn)。

我的服務(wù)器連接網(wǎng)絡(luò)，每次都要經(jīng)過(guò)一個(gè)計(jì)費(fèi)網(wǎng)管，所以setCircularRedirectsAllowed必須保留

當(dāng)然會(huì)發(fā)生多次重定向，

很奇怪的是，程序在winxp上開(kāi)發(fā)運(yùn)行沒(méi)有問(wèn)題，移植到solars10 上后就報(bào)錯(cuò)了

請(qǐng)各位多指點(diǎn)
