I need to check that our visitors are using HTTPS. In BasePage I check if the request is coming via HTTPS. If it's not, I redirect back with HTTPS. However, when someone comes to the site and this function is used, I get the error:
System.Web.HttpException: Server
cannot append header after HTTP
headers have been sent. at
System.Web.HttpResponse.AppendHeader(String
name, String value) at
System.Web.HttpResponse.AddHeader(String
name, String value) at
Premier.Payment.Website.Generic.BasePage..ctor()
Here is the code I started with:
// If page not currently SSL
if (HttpContext.Current.Request.ServerVariables["HTTPS"].Equals("off"))
{
// If SSL is required
if (GetConfigSetting("SSLRequired").ToUpper().Equals("TRUE"))
{
string redi = "https://" +
HttpContext.Current.Request.ServerVariables["SERVER_NAME"].ToString() +
HttpContext.Current.Request.ServerVariables["SCRIPT_NAME"].ToString() +
"?" + HttpContext.Current.Request.ServerVariables["QUERY_STRING"].ToString();
HttpContext.Current.Response.Redirect(redi.ToString());
}
}
I also tried adding this above it (a bit I used in another site for a similar problem):
// Wait until page is copletely loaded before sending anything since we re-build
HttpContext.Current.Response.BufferOutput = true;
I am using c# in .NET 3.5 on IIS 6.
