ASP.net redirection 

The easiest way to make a redirection in ASP.NET is using Response.Redirect(url). What it actually does is, that it creates a response with the "302 (Object Moved)" status code and the target destination.

If the page is permanently moved, then the 302 status code is no longer correct. Search engines also looks at 301 and 302 redirects differently. Here's a quote from The Internet Digest: There is no natural way of doing a 301 redirect in ASP.NET, so you have to set the HTTP headers manually. Below given is a small method that illustrates how to do it. All you have to do is to call it from the Page_Load or preferably from Page_Init or in ASP.NET 2.0 Page_PreInit.

You need this to size the black vertical bar that attaches to the mouse correctly when performing an actual resize. 2.Based on how the code is written, you can only perform resize operations on table header cells (TH tags). This simply feels like the right way to do it - you could make it TD tags instead, and be able resize the column for the entire height of the table if you wanted to. 3.The actual table must have a style set of "table-layout: fixed;" If you don't set this style, strange things happen (try it and see, it goes all loopy when you resize . 4.To save having to remember to put too many requirements in the implementation, the black ve ...
