Session 19Configuring an Application in ASP.NET Exploring ASP.NET / Session 19 / 2 of 31ReviewA service has two characteristics: Interface and Registration.Web services reduce the “communication-gap” among the Web applications, enhancing interactivity. Web sites thereby group together to form a constellation, providing users a rich user experienceAdvantages of Web ServicesCross business integrationImproved efficiencyCloser customer relationshipsFacilitation of just-in-time integrationThe extension of a Web service file in .NET is .asmx.The [WebMethod] tag notifies the ASP.NET compiler that the method to follow should be a Web method, which is to be exported onto the Web.A proxy class can be created from any WSDL file. Exploring ASP.NET / Session 19 / 3 of 31Review contd A Web service could be called from a browser, an ASP page or even another Web service. Using the browser, the Web service can be accessed using either HTTP-GET or HTTP-POST. A SOAP request from an ASP page, or a Web service to another Web service can also be made.WSDL is the short form for Web Services Description Language. WSDL is the grammar for a Web service, or moreover, could be thought of as a language that describes or portrays a Web service.The proxy class does not contain any application logic. Instead, it contains the transporting logic as to how the parameters would be passed, and the result retrieved.The proxy class will also contain a list of all the methods that are present in the Web service and their prototypes.UDDI is the abbreviation for Universal Description, Discovery and Integration.UDDI helps in registering the services provided by the service providers, so that they can be shared. It also helps the service consumers or Web users in locating the Web services. Exploring ASP.NET / Session 19 / 4 of 31ObjectivesDiscuss Machine.ConfigDiscuss Web.ConfigDiscuss the structure of a configuration fileSecure your web pages using Authentication Exploring ASP.NET / Session 19 / 5 of 31Web Pages – Web ApplicationIndividual web pages together form a web applicationAdvantage of grouping individual pages together into an application, is that values can be set for all these pages at once, by setting the properties of the application The setting of values for the properties of an application that will control the application at runtime, is known as configuring the ASP.NET application Web PageWeb PageWeb PageWeb PageWeb Page------------------WEB APPLICATION Exploring ASP.NET / Session 19 / 6 of 31Configuration FilesIn ASP.NET, all that needs to be done to configure an application, is to create a configuration file called web.config, and place it in the root directory of the application This web.config is an XML based file <configuration><system.web><sessionState timeout=”20” /></system.web></configuration> ASP.NET provides the configuration files that are needed to customize the web site. These files offer remarkable flexibility to the web applications Exploring ASP.NET / Session 19 / 7 of 31Features of Configuration FilesStored in plain text formatWritten in XML. Rules for naming tags and attributesNo need to restart server in case of changes to fileEach directory overrides earlier configuration fileClients cannot view the file from browser Exploring ASP.NET / Session 19 / 8 of 31Rules for naming the TagsPascal-case : first character is uppercase, and the first letter of any subsequent concatenated words is uppercase. Exceptions being true and false, which are in lowercase.Attribute valuesCamel-cased : First character of a tag name is lowercase, and the first letter of any subsequent words is uppercaseTag and attribute namesRuleType of Tags Exploring ASP.NET / Session 19 / 9 of 31Types of Configuration FilesMachine.config Decides configuration for all the applications residing on the server Settings are applied to single application residing on the server XML based file is Stored in C:\WinNT\Microsoft.NET\Framework\v.1.xxxx\config Build number of .net CLRWeb.config Only one file per ASP.NET installation on a machine XML based file stored in the web application directory of the web server One file per each directory of the web application Exploring ASP.NET / Session 19 / 10 of 31Types of Configuration Files – Contd…Web Applications One per machineOne per applicationOverride settings of machine.config [...]...
