ASP.Net - Help translating code in Pade_Load event

Good Day Experts!

I am back on my journey to learning ASP.Net.  Currently, I am a VB.Net programmer.
I have attached a text file with code that is in the Page_Load event for the Login.aspx of the website.  

Can you help and translate what is happening in the code?  Also, "If Not Page.IsPostBack Then"...will it ever be Page.IsPostBack and not run the code? Also, "If Not Request.Cookies("myCookie") Is Nothing Then"...will the cookies ever not be nohting?

Thanks,

What file?  : )

Then"...will it ever be Page.IsPostBack and not run the code?
Yes. The first time a page is requested is not a post back. Clicking a button or interacting with some other control on the page (typically) triggers a post back.

Also, "If Not Request.Cookies("myCookie") Is Nothing Then"...will the cookies ever not be nohting?
Sure.

"If Not Page.IsPostBack" is checking as to whether or not the page is being initially requested (e.g. a user types the URL into the browser's address bar). If this is the initial request of the page, then the session is cleared (just in case an existing session is still in memory, I presume). Then you are checking to see if the browser sent a cookie named "myCookie". If it did, then you extract the cookie from the request object. From this cookie you are extracting the values of the "ITSusername", "ITSP", "AMARKN" (commented out), and "ITSR" fields, and using them to set up the states of various controls (e.g. text boxes and check boxes). Finally, you are checking a code-behind field named "ModError" for any text. If it has text, then its text is placed into a label on the page.

Excellent, thanks for the explanation.  My next step of working through the code I put a breakpoint on the first line behind the login button.  After entering my username and password and I click the Login button...to my surprise the first line of code that is executed is in the Page_Load event of the Login.aspx!  So, once I am in the website I hit the Logout button and same thing...to my surprise the first line of code that is executed is in the Page_Load event of the Login.aspx!  I can't figure out why it happens and where in the code it tells it to go back to the Page_Load event of the Login.aspx page.

Do you have any thoughts that might help me understand?

Thanks,
