How to edit word document using Asp.Net?

How to edit word document using Asp.Net?

Problem -
 
Editing word document is not an easy task in ASP.Net, because we don't have any direct option to open server copy of word document. When we open any word document from server machine then first that document is downloaded to client machine's temp folder and then it is displayed. So if we will make any changes to that opened document then that changes will be saved in only client machine not in server machine.
 
Means the changes will not be reflected directly to server copy of word document.   
 
I have done some RND in this problem and came with one workaround. Hope this solution will help you.

How to disable back button of browser.

This is common requirement for all the web application to disable back button of browser after log-out. But there is no direct method or property to disable back button of browser. This only depends on browser cache or history, if browser contains any history or cache then back button will be active after log-out also.

Here I am explaining - How to disable back button of browser?

This can be possible using only after clearing history or cache of browser.
or
Don't allow browser to keep history or cache.

For this we can add this code for all the pages to which we don't want to allow cache.

Here is code-

  protected void Page_Load(object sender, EventArgs e)
        {
            Response.Buffer = true;
            Response.ExpiresAbsolute = DateTime.Now.AddDays(-1d);
            Response.Expires = -1000;
            Response.CacheControl = "no-cache";
        }


 In this code, I am written code to disallowing browser to cache the page. So that even after browsing the page browser will not keep page as cache or history.

This code should be included for all the pages.
