ASP traverses some objects (request, session, Application)

1. Traverse request
Method 1:
<%
For each R in request. querystring
Response. Write "Request (" "& R &" ") =" & request (r)
Response. Write "<p>"
Next
%>
Method 2:
<%
For I = 1 to request. querystring. Count
Response. Write "Request (" "& request. querystring. Key (I) &" ") =" & request. querystring (request. querystring. Key (I ))
Response. Write "<p>"
Next
%>
Change querystring to form to traverse the post variable.
2. Traverse sessions
<%
Session ("key1") = "value1"
Session ("key2") = "value2"
For each s in session. Contents
Response. Write "Session (" "& S &" ") =" & session (s)
Response. Write "<p>"
Next
%>
3. Traverse Application
<%
Application ("key1") = "value1"
Application ("key2") = "value2"
For each a in application. Contents
Response. Write "application (" "& A &" ") =" & Application ()
Response. Write "<p>"
Next
%>
