Application Security Testing: An Integral Part of DevOps

Execute Code Only Once the First Time it is Called

You may need to execute a portion of code in a function only once the first time it is called. The following fragment illustrates an easy way to do this:
static bool bExecuted = false;
if (!bExecuted)
  //write the code to be executed once here.
   bExecuted = true;

**NOTE: This code works only in a single threaded environment.
