host header

[randy_belcher]

Is it possible to capture the host header in the global.asax application_start event?

I would like to set some application variables based on the host header. Like using a test database connection string if the host header is localhost or use live data if the host header is production.

Thanks.

Dim currentContext As System.Web.HttpContext = System.Web.HttpContext.Current
Dim hostIPAddess As String

If Not currentContext Is Nothing Then
     hostIPAddress = currentContext.Request.UserHostAddress
End If

This just returned the IP (127.0.0.1). I am looking for the url
http://xxx/yyy/site.com
or just the host header which is the xxx part.

I tried userhostname and it returned (127.0.0.1) too.

Thanks for the help.

you can use the Request Object. It has properties like Request.Url, Request.HostName.....

that doesn't work in the global.asa in the application_start event. I am going to check the code above on the server instead of my local machine and see if it works.

even on the server i just get the IP address using the above code. any other suggestions

got it. the answer is

strhostIPAddess = currentContext.Request.Url.Host

thanks for the help guys. you pointed me to the direction I needed to go.
