  1. Session 14 Configuring an ASP.net Application Building Applications using ASP.NET and C# / Session 14 / 1 of 18

  2. Session Objectives • Discuss: • Machine.Config • Web.Config • Structure of a configuration file • Secure your web pages using Authentication Building Applications using ASP.NET and C# / Session 14 / 2 of 18

  3. Web Pages – Web Application Web Page Web Page Web Page WEB APPLICATION Web Page Web Page --------- --------- Building Applications using ASP.NET and C# / Session 14 / 3 of 18

  4. Configuration Files <configuration> <system.web> <sessionState timeout=”10” /> </system.web> </configuration> • Stored in plain text format Tag and attribute names • Written in XML. Rules for • naming tags and attributes Attribute values • No need to restart server in case of changes to file F E A T U R E S • Each directory can have its own file • Each directory overrides earlier configuration file • Clients cannot view the file from browser Building Applications using ASP.NET and C# / Session 14 / 4 of 18

  5. Types of Configuration Files - 1 Machine.config • Settings are applied to all the applications residing on the server Build number of .net CLR • XML based file • Stored in C:\WinNT\Microsoft.NET\Framework\v.1.xxxx\config • Only one file per ASP.net installation on a machine Web.config • Settings are applied to single application residing on the server • XML based file • One file per each directory of the web application Building Applications using ASP.NET and C# / Session 14 / 5 of 18

  6. Types of Configuration Files - 2 • One per machine Web Applications • One per application • Override settings of machine.config Building Applications using ASP.NET and C# / Session 14 / 6 of 18

  7. Typical Web.config File Configuration section Handler Declaration Area <configuration> <configSections> <section name="sectionSettings" type="Class" /> <sectionGroup name="sectionGroup"> <section name="sectionSettings" type="Class" /> </sectionGroup> </configSections> <section name=”sectionSettings” type=<Class>” /> <sectionGroup> <sectionSettings attribute="someValue" /> <sectionSettings SomeAttribute=”SomeValue”> <element attribute=”value”> </sectionSettings> </sectionGroup> </configuration> Configuration section Settings Area Building Applications using ASP.NET and C# / Session 14 / 7 of 18

  8. Page Configuration Setting Response to the client can be buffered <configuration> <system.web> <pages buffer=”false” enableViewState=”true” /> </system.web> </configuration> View state can be set Building Applications using ASP.NET and C# / Session 14 / 8 of 18

  9. Application Setting Configuration settings in form of key-value pair <configuration> <appSettings> <add key=”MyQuery” value=”Select * FROM MyTable”/> </appSettings> </configuration> The settings are read in ASP.NET page ... String GetQuery = Configuration.AppSettings(“MyQuery”); ... Building Applications using ASP.NET and C# / Session 14 / 9 of 18

  10. Compilation Setting Specifies whether to compile retail binaries or debug binaries. <configuration> <system.web> <compilation debug="true" defaultLanguage=”C#”/> </system.web> </configuration> Provides a semicolon-separated list of language names to use in dynamic compilation of files Building Applications using ASP.NET and C# / Session 14 / 10 of 18

  11. Sub-tags of Compilation tag -1 1 <assemblies> sub-tag add remove clear <configuration> <system.web> <compilation debug="true" defaultLanguage=”C#”/> <assemblies> <add assembly="System.Net" /> </assemblies> </system.web> </configuration> Building Applications using ASP.NET and C# / Session 14 / 11 of 18

  12. Sub-tags of Compilation tag - 2 2 <namespaces> sub-tag <configuration> <system.web> <compilation debug="true" defaultLanguage=”C#”/> <namespaces> <add namespace="System.Web.UI" /> </namespaces> </system.web> </configuration> 3 <compilers> sub-tag Building Applications using ASP.NET and C# / Session 14 / 12 of 18

  13. customErrors Setting <customErrors defaultRedirect="url" mode="On|Off|RemoteOnly"> <error statusCode="statuscode"redirect="url“/> </customErrors> Syntax <configuration> <system.web> <customErrors defaultRedirect="http://localhost/allError.aspx" mode="RemoteOnly"> <error statusCode="404" redirect=“http://localhost/Error404.aspx"/> </customErrors> </system.web> </configuration> Example Building Applications using ASP.NET and C# / Session 14 / 13 of 18
