• How to achieve syncronization in loadbalanced multiserver environment

  - by Anoop

  Hi, I have to create a .net web application which would run on more than one front end server which are load balanced. Now I have to use some third party api which is not thread safe so only one thread should call the API at a time so I have to some use syncronization machanism like lock or mutex which provide syncronisation within the process and across the process in machine.Now will lock or mutex work in loadbalanced multiserver environment correctly? If not then is there any mechanism using which I can syncronise all the threads in all the machines??
