Question

I created simple HttpModule, all what I need is just get is valid Sitecore.Context inside but during processing I see that my Sitecore.Context is some kind of default.

I can get Sitecore user that log in to Sitecore, etc.
How to fix it ?

Answer 1

I assume you have a Sitecore Context, but it is null or set to the wrong site or language.
You can change the context like this:

// switch to the preferred site    
Sitecore.Context.SetActiveSite("yourSiteName");

// set the preferred database
Sitecore.Context.Database = Sitecore.Configuration.Factory.GetDatabase("master");

// set the preferred language
Language language =  Sitecore.Globalization.Language.Parse("en");
Sitecore.Context.SetLanguage = (language, false);

You probably also want to switch back to the original settings after your processing is done. So it is wise to “save” the original settings in a variable so you can change them back afterwards
