Cacheability

It could be sometimes usefull to prevent some web pages from being cached by the web browser
so that when you use the back button of the browser you get the latest output from the server and not a cached one. Now we are going to see the main actions necessary for performing this task.

In order to improve performance and because the experience has proven it's utility : web browsers generaly keeps cache of web pages they visit.

If we nedd to stop such behavior here the way:

Response.Cache.SetCacheability (HttpCacheability.NoCache);
Response.Cache.SetAllowResponseInBrowserHistory(false);

You may add these lines in the Page.Load event handler to see immediately the result.
The firts method controls how documents are cached on the cache capable device by setting the Cache-Control HTTP header.

"The second method SetAllowResponseInBrowserHistory indicates whether the response will be kept in browser History. Passing the value of false means the output will not be held in browser history"

This article has been very usefull for me so thank you Bipin Joshi from dotnetbips (http://www.dotnetbips.com/) for publishing it.

Sql Server adapters for Biztalk Server One of the greatest difficulties I found when I started working with BizTalk 2004 was the lack of documentation about the SQL Adapter. In this article, I'm going to demonstrate how we can use this adapter in an Orchestration of BizTalk. The Example To build this example, we're going to use the Northwind database. We're going to simulate a hypothetical situation where we receive an XML message as a file, containing the order number, a customer ID, and the date of the order. In the orchestration, we will use SQL Server to search the additional information about the customer, using the SQL Adapter. Creating the Project We'll start this article by creating a new BizTalk Server project in Visual Studio. In the Visual Studio .NET menu, select the "New Project" option, and for the type of project, select "BizTalk Projects". Select the template "Empty BizTalk Project" and create a project named OrderManager.

Writing effective adapters for Biztalk Server Introduction Many people, both within Microsoft and in third-party companies, have written successful adapters for Microsoft® BizTalk® Server. This task can be difficult, and this paper is intended to present some of the "tricks of the trade" that these developers have learned, in the hope that these will help others avoid common problems. This document is structured as a set of issues that programmers face when writing adapters, and provides guidelines for resolving these issues. These guidelines can be read in any order, although you may find that reading the whole document first will make the individual guidelines easier to understand. Effective Writing for Adapters Much of the complexity in writing adapters for BizTalk Server is centered on the problems of batched operations and that is what we will look at first. Operations, Messages, Batching, and Transactions Adapters commonly support sending messages to and receiving messa
