5. Test. Open the browser and enter http: // 192.168.6.121/index. jsp.
Session shows that aXXXXX accesses the 121 server, that is, server1, because it is the first access, so the Cookie is not obtained. refresh it and check whether it will access 162 server2.
After refresh N times, it is still 121, that is, the patch takes effect, and the cookie value is also obtained. To test, I opened another Firefox browser because of session and cookie issues.) enter the URL:
The display is 162. The session value starts with bXXX. After refresh N times:
Still 162 server 2 server !! If you have any questions during the test, you can remove the srun_id = a srun_id = B in the nginx configuration file. Then, you will know that the page is accessed by polling !! The patch I uploaded is decompressed on linux. Because 51cto does not support the gz format, I changed the suffix, run shell $> tar zxvf nginx-upstream-jvm-route-read-only.rar on linux! The solution for tomcat is README:1. For resinJvm_route $ cookie_JSESSIONID | sessionid reverse;
