Usually authentication&authorization processes are performed by built-in cookie and token supports in .net MVC. But if you decide to do it yourself with Session you can use below logic for both page requests and ajax requests.

This is an example of how to use the generic type TFood inside Eat method on the class Animal
public interface IFood
{
void EatenBy(Animal animal);
}
public class Grass: IFood
{
public void EatenBy(Animal animal)
{
Console.WriteLine("Grass was eaten by: {0}",...
arr = np.arange(7)
print(arr)
# Out: array([0, 1, 2, 3, 4, 5, 6])
Comparison with a scalar returns a boolean array:
arr > 4
# Out: array([False, False, False, False, False, True, True], dtype=bool)
This array can be used in indexing to select only the numbers greater than 4:
arr[arr&...
The numpy.reshape (same as numpy.ndarray.reshape) method returns an array of the same total size, but in a new shape:
print(np.arange(10).reshape((2, 5)))
# [[0 1 2 3 4]
# [5 6 7 8 9]]
It returns a new array, and doesn't operate in place:
a = np.arange(12)
a.reshape((3, 4))
print(a)
# ...
Along with classic way of route definition MVC WEB API 2 and then MVC 5 frameworks introduced Attribute routing:
public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
// This...
Currying, according to Wikipedia,
is the technique of translating the evaluation of a function that
takes multiple arguments into evaluating a sequence of functions.
Concretely, in terms of scala types, in the context of a function that take two arguments, (has arity 2) it is the conversion o...
Draw samples from a normal (gaussian) distribution
# Generate 5 random numbers from a standard normal distribution
# (mean = 0, standard deviation = 1)
np.random.randn(5)
# Out: array([-0.84423086, 0.70564081, -0.39878617, -0.82719653, -0.4157447 ])
# This result can also be achieved with t...
.htaccess can be used to set a custom error pages that matches the theme of your website instead of seeing a white error page with black techno-babble when users end up on at a page with an error server response code. The error page can be any browser parseable file, including (But not limited to)...

The following method computes the Nth Fibonacci number using recursion.
public int fib(final int n) {
if (n > 2) {
return fib(n - 2) + fib(n - 1);
}
return 1;
}
The method implements a base case (n <= 2) and a recursive case (n>2). This illustrates the use of re...
Overload resolution partitions the cost of passing an argument to a parameter into one of four different categorizes, called "sequences". Each sequence may include zero, one or several conversions
Standard conversion sequence
void f(int a); f(42);
User defined conversion seque...
If your class doesn't implement a specific overloaded operator for the argument types provided, it should return NotImplemented (note that this is a special constant, not the same as NotImplementedError). This will allow Python to fall back to trying other methods to make the operation work:
When...
While
The most trivial loop type. Only drawback is there is no intrinsic clue to know where you are in the loop.
/// loop while the condition satisfies
while(condition)
{
/// do something
}
Do
Similar to while, but the condition is evaluated at the end of the loop instead of the beginn...
