上面两篇文章说了http协议和IIS处理,这次说下当IIS把请求交给Asp.net后的过程。
AppManagerAppDomainFactory
当IIS把请求交给asp.net时候,如果AppDomain还不存在则创建APPDomain,将AppDomain指派给与请求对应的应用程序,这通过AppManagerAppDomainFactory类中的Create方法实现,代码如下:
public Object Create(String appId, String appPath) { try { if (appPath[0] == '.') { System.IO.FileInfo file = new System.IO.FileInfo(appPath); appPath = file.FullName; } if (!StringUtil.StringEndsWith(appPath, '\\')) { appPath = appPath + "\\"; } ... ISAPIApplicationHost appHost = new ISAPIApplicationHost(appId, appPath,false); //创建环境,包括编译环境 ISAPIRuntime isapiRuntime = (ISAPIRuntime)_appManager.CreateObjectInternal(appId, typeof(ISAPIRuntime), appHost, false, null); isapiRuntime.StartProcessing(); return new ObjectHandle(isapiRuntime); } catch (Exception e) { &n
