how common controller call every time when any event is fired in nopcommerce 3.90

Hello, I am new in nopcommerce want some help.

I want to know, that how common controller is called when any event is fired in nopcommerce 3.90.

For more clear let we take one example, i.e.

when I click the login button in nopcommerce web page at that time login httppost method is fired which is in customer controller and then after it fired the AdminHeaderLinks method[in this method it shows the administration link] which is in common controller[I know by doing in debug mode]. I search in customer controller and other pages but I didnt find any link which shows that from their the common controller page is calling.

So, for that I am confuse that how the common controller is calling every time in any event.

Please help me to solve this confusion.

Thank You.

Hi,

When any page is load than below methods are required to load

Logo,
LanguageSelector,
CurrencySelector,
TaxTypeSelector
HeaderLinks,
Footer
Favicon,

So that call on every times from header.cshtml page in_root.cshtml

So that all methods are call on every click.

Thanks
