Файл Web.config
В ранних версиях Windows конфигурационные данные хранились в ini-файлах, на смену которым пришел глобальный реестр. В ASP.NET приложения фактически возвращаются к временам текстовых ini-файлов – конфигурационные данные хранятся в текстовом файле Web.config, находящемся в каталоге приложения. Этот файл определяет условия выполнения приложений ASP.NET – такие как параметры отладки и системы безопасности. Конфигурационные файлы имеют довольно сложную структуру. Ниже приведено содержимое файла Web.config для предыдущего примера:
1 <?xml version-"1.0" encoding="utf-8"?> 2 <configuration> 3 <system.web> 4 <!--DYNAMIC DEBUG COMPILATION 5 Set compilation debug="true" to insert debugging symbols (.pdb 6 information)into the compiled page.Because this creates a larger file 7 that executes more slowly,you should set this value to true only when 8 debugging.and to false at all other times.For more information,refer 9 to the documentation about debugging ASP.NET files. 10 › 11 compilation defaultl_anguage="vb" debug="true"/> 12 <!--CUSTOM ERROR MESSAGES 13 Set customErrors mode="0n" or "RemoteOnly" to enable custom error 14 messages.
