After the porttunnel port ing, obtain the Internet IP Address

When I opened the background management of the website, I found that the IP address obtained using request. getremoteaddr () was changed to the new fixed IP address of the Internet Web server. Open the HTTP settings of porttunnel and you will see "add X-client-address to request message". It seems a bit interesting. check it in front and restart the Web ing project, then, a new JSP is created in the website background to enumerate the webpage header information. In the output information, X-client-Address: XXX is displayed. xxx. xxx. XXX, which is exactly the IP address of the client I need. Next it's easy to put the request. change getremoteaddr () to request. getheader ("X-client-address") is OK,

C # httpcontext. Current. Request. headers ["X-client-address"]
