asp.net - Handling application-wide events without Global.asax -

my project has no "global.asax" various reasons , can't change (it's component). also, have no access web.config, httpmodule not option.

is there way handle application-wide events, "beginrequest" in case?

i tried , didn't work, can explain why? seems bug:

httpcontext.current.applicationinstance.beginrequest += mystaticmethod; 

no, not bug. event handlers can bound httpapplication events during ihttpmodule initialization , you're trying add somewhere in page_init(my assumption).

so need register http module desired event handlers dynamically. if you're under .net 4 there news - there preapplicationstartmethodattribute attribute (a reference: three hidden extensibility gems in asp.net 4):

this new attribute allows have code run way in asp.net pipeline application starts up. mean way early, before application_start.

so things left pretty simple: need create own http module event handlers want, module initializer , attribute assemblyinfo.cs file . here module example:

public class mymodule : ihttpmodule {     public void init(httpapplication context)     {         context.beginrequest += new eventhandler(context_beginrequest);     }      public void dispose()     {      }      void context_beginrequest(object sender, eventargs e)     {      } } 

to register module dynamically use dynamicmoduleutility.registermodule method microsoft.web.infrastructure.dll assembly:

public class initializer {     public static void initialize()     {         dynamicmoduleutility.registermodule(typeof(mymodule));     } } 

the thing left add necessary attribute assemblyinfo.cs:

[assembly: preapplicationstartmethod(typeof(initializer), "initialize")]
