Dear Oleg, Thanks a lot for your reply. I look forward to future versions that can really fix this.
I found that implementing a HttpRequestRetryHandler doesn't seem to be a valid workaround, since I couldn't find proxy information in the HttpContext object passed to retryRequest(), which means that I can't figure out which proxies are failing. I am planning to create for each proxy in my proxy list an HttpClient, and manually manage this list of HttpClient's. --- Cheers, Tom 在 2012年4月14日 上午3:00，Oleg Kalnichevski <[email protected]> 写道： > On Fri, 2012-04-13 at 20:43 +0800, 董玉冰 Tom Yubing Dong wrote: >> Hi, >> >> I have implemented my own ProxySelector, so that when connection >> fails, connectFailed is called and the proxy can be suspended or >> removed from the list. >> >> I used my ProxySelector implementation to construct a >> ProxySelectorRoutePlanner, and set it to be the RoutePlanner of a >> DefaultHttpClient. >> >> I let ProxySelector.select return an invalid proxy (like >> "localhost:1234").
