Urgent: C++ Webservice call

Hi Guys
I have a small piece of C++ code which is used as a plugin in my product. I just need to compile this piece of code and put the .so file in my main product's lib for the plugin to work properly.

My problem is that now I want to make a Rest webservice call from this C++ plugin file. I cannot add a webservice reference by using Visual studio as its not a project.

Can anyone suggest some way to implement this requirement in the best possible way. Please respond.

Thanks for your help.

If you are not using MFC or .NET, you should start from socket。
