Request Object:
Request has five (5) Collections, one (1) Property, and one (1) Method. You'll use the Collections far more than the property or the method.
Request Collections:
Below is a table of the Request Collections and descriptions of how they are used.
| ClientCertificate | Request.ClientCertificate("Key[Field]") Client security info for SSL encryption |
| Cookies | Request.Cookies("cookieName") Holds cookie value stored on the client |
| Form | Request.Form("formName") Holds value sent via HTML Form |
| QueryString | Request.QueryString("keyName") Name/Value pair appended to the end of the URL |
| ServerVariables | Request.ServerVariables("variableName") Hold values sent in the HTTP Headers |
ClientCertificate:
Request.ClientCertificate is used with S.S.L. (Secure Sockets Layer). It is beyond the scope of this web site.
Cookies:
We will learn Request.Cookies and Response.Cookies together in Lesson 08. Please be patient.
Form:
Request.Form is probably the workhorse of the Request Collections. The first script is a repeat from Lesson 03.
<%@LANGUAGE="JavaScript"%><%//No ASP Here, just a regular HTML Page%><HTML><STRONG>Type something into the text box and submit it.</STRONG><FORM ACTION="script08a.asp" METHOD="Post"><INPUT TYPE="Text" NAME="WebPageVariable"><BR><STRONG>How Much Money do you make each month?</STRONG><BR><SELECT NAME="monthlySalary"><OPTION>Under $5,000,000</OPTION><OPTION>Above $5,000,000</OPTION><OPTION>Nobody's darn business.</OPTION></SELECT><BR><INPUT TYPE="Submit" VALUE="Submit"></FORM></HTML>
Click Here to run script08.asp in a new window. It posts information to script08a.asp which is found below. In turn, script08a.asp posts information to script08b.asp which is also found below.
<%@LANGUAGE="JavaScript"%><%var WebPageVariable = new String( Request.Form("WebPageVariable") )WebPageVariable = WebPageVariable.toUpperCase();var monthlySalary = new String( Request.Form("monthlySalary") )monthlySalary = monthlySalary.toLowerCase();%><HTML>The Web Page Variable you typed is: <%=WebPageVariable%> <BR>The monthly salary you listed is: <%=monthlySalary%> <BR><FORM ACTION="script08b.asp" METHOD="Get"><INPUT TYPE="hidden" VALUE="<%=monthlySalary%>" NAME="QueryVariable"><STRONG>Click the button to see Query Strings</STRONG><BR><INPUT TYPE="submit" VALUE="Submit"></FORM></HTML>We'll be using Request.Form when we "Post" an HTML form to the server. Notice that the NAME attribute in the HTML form corresponds to the "name" in
