set nonProxyHosts in Apache HttpClient 4.1.3

阅读更多关于 set nonProxyHosts in Apache HttpClient 4.1.3

问题 I just cant help myself by answering this question. How can I set nonProxyHosts in the Apache HttpClient 4.1.3? In the old Httpclient 3.x that was quite simple. U could just set it using the setNonProxyHosts methods. But now, there's no equivalent method for the new version. I have been looking trough the api docs, tutorials and examples and havent found the solution so far. to set a normal proxy u can just do it by this: HttpHost proxy = new HttpHost("127.0.0.1", 8080, "http");

Header values overwritten on redirect in HTTPClient

阅读更多关于 Header values overwritten on redirect in HTTPClient

I'm using httpclient 4.2.5 to make http requests which have to handle redirects as well. Here is a little example to understand the context: A sends http request (using httpclient 4.2.5) to B B sends 302 redirect (containing url to C) back to A A follows redirect to C C retrieves request URL and do some work with it If C parses the request URL by request.getRequestURL() (HttpServlet API) it contains e.g. host and port of the original request from step 1, which is wrong. The problem exists in step 2, where httpclient handles the redirect. It just copies all headers from the original request

问题 We have some code written using commons-httpclient-3.1 that needs to be converted to 4.1. I'm only somewhat familiar with this and am reading the 4.1 httpclient tutorial now. I see a couple of posts here (e.g. Converting from HttpClient 3 to 4 but that's about a specific construct). Seems like there should be some docs/examples somewhere showing how to upgrade usage of 3.x to 4.x ? One specific example: replacing use of org.apache.commons.httpclient.HttpState 回答1: I would replace the library
