What is the difference between HTTP method Get and Post?

GET Method:

2.It’s not secured as submitted text is visible in plain text format in the Location bar of the web browser.
3.Length of the submitted string is restricted.

POST Method:

1.All the name value pair’s are submitted in the Message Body of the request structure.
2.Length of the string (amount of data submitted) is not restricted or limited.

What are the 3 different ways to globalize web applications?

Detect and redirect approach : In this approach we create a separate Web application for each supported culture, and then detect the user’s culture and redirect the request to the appropriate application. This approach is best for applications with lots of text content that requires translation and few executable components.
Run-time adjustment approach : In this approach we create a single Web application that detects the user’s culture and adjusts output at run time using format specifiers and other tools. This approach is best for simple applications that present limited amounts of content.
Satellite assemblies approach : In this approach we create a single Web application that stores culture-dependent strings in resource files that are compiled into satellite assemblies. At run time, detect the user’s culture and load strings from the appropriate assembly. This approach is best for applications that generate content at run time or that have large executable components.

What are the steps to follow to get user's culture at run time?

To get the user’s culture at run time, follow these steps:
1. Get the Request object’s UserLanguages property.
2. Use the returned value with the CultureInfo class to create an object representing the user’s current culture.
For example, the following code gets the user’s culture and displays the English name and the abbreviated name of the culture in a label the first time the page is displayed:
private void Page_Load(object sender, System.EventArgs e)
{ // Run the first time the page is displayed if (!IsPostBack) { // Get the user's preferred language.
string sLang = Request.UserLanguages[0]; // Create a CultureInfo object from it.
CultureInfo CurrentCulture = new CultureInfo(sLang);
lblCulture.Text = CurrentCulture.EnglishName + ": " + CurrentCulture.Name;
}
}
