Old Skool - Classic ASP ServerVariables List
This is an oldie but a goodie – I don’t know how many times in my career I’ve rewritten these few lines of code but I’ve preserved it here to save me writing it yet again! A simple method for outputting all the server variables, query string parameters and form variables in Classic ASP!
Dim variableName
for each variableName in Request.ServerVariables
response.write(variableName & ": " & Request.ServerVariables(variableName) & "<br/>")
next
response.Write("<hr/>QUERY STRING COLLECTION<br/>")
for each variableName in Request.QueryString
response.write(variableName & ": " & Request.QueryString(variableName) & "<br/>")
next
response.Write("<hr/>FORM COLLECTION<br/>")
for each variableName in Request.Form
response.write(variableName & ": " & Request.Form(variableName) & "<br/>")
next
response.Write("<hr/>SESSION COLLECTION<br/>")
for each variableName in Session.Contents
response.write(variableName & ": " & Session(variableName) & "<br/>")
next

Useful code to properly record and redirect an unhandled exception from Global.asax Application_Error Handler
void Application_Error(object sender, EventArgs e)
{
// Code that runs when an unhandled error occurs
string httpCode = ((HttpException) Server.GetLastError()).GetHttpCode().ToString();
if (HttpContext.Current.Session != null)
{
HttpContext.Current.Session["LastError"] = Server.GetLastError();
Server.ClearError();
}
switch (httpCode)
{
case "404":
Response.Redirect("/Error/Error404.aspx");
break;
default:
Response.Redirect("/Error/Error.aspx");
break;
}
}
