<form action="somepage.asp" method=POST>
   <input type ="text" value ="somevalue" name ="somevariable">
   <input type=submit>
</form>

Supports more characters than GET or PUT
The page the form is submitted to will not show the parameters in the address window

The ASP page the form is submitted to uses the following code to retrieve the variable

<% somevariable = Request.Form("somevariable") %>

Using a Form with GET or PUT

<form action="somepage.asp" method=GET>
   <input type ="text" value ="somevalue" name ="somevariable">
   <input type=submit><input type=reset>
</form>

The number of characters is limited
The page the form is submitted to will show the parameters in the address window
The ASP page the form is submitted to uses the following code to retrieve the variable

<% somevariable = Request.Querystring("somevariable") %>

Something To Think About
You can simply use Request("somevariable") and it will retrieve it from the header no matter which of the 3 methods you used. This is probably a little slower but it makes for easier coding if you are not worried about milliseconds of time savings.

Also some versions of IE on the MAC do not work with "PUT" and will give you a 404 error, so it is probably best just to use "GET" though it is definitely a bug that they never seem to fix.

And often it's nice to have pages "post back" to themselves and then handle further processing from there.  This can often cut down on the number of pages that need to be developed and the related back-and-forth involved with many pages.

To make the form post back to the same page:
<form id="frmMain" name="frmMain" action="<%= Request.ServerVariables("SCRIPT_NAME") %>" method="post">

And here are some buttons:
<% ' *** btnClose %>
<input type="submit" name="btnClose" value="Close">
<% ' *** btnSave %>
<input type="submit" name="btnSave" value="Save">
<% ' *** btnNew %>
<input type="submit" name="btnNew" value="New">
<% ' *** btnDel %>
<input type="submit" name="btnDel" value="Delete" onclick="return confirm('Are you sure you want to delete this record?');">

To handle processing toward the top of the page:
If Request.Form("btnClose") <> "" Then  ' Close btn.
 ' Close.
 Call ClosePg()
Elseif Request.Form("btnSave") <> "" Then  ' Save btn.
 ' Set var.
 Call SetVar("frompost")

 ' Save rec.
 Call SaveRec()
Elseif Request.Form("btnNew") <> "" Then  ' New btn from this pg.
 ' Set var.
 Call SetVar("new")
Elseif Request.Form("btnDel") <> "" Then  ' Del btn.
 ' Set var.
 Call SetVar("frompost")

 ' Del rec.
 Call DelRec()

 ' Set var.
 Call SetVar("new")
Elseif Request.QueryString("CustID") <> "" Then ' CustID from Many pg.
 ' Set var.
 Call SetVar("fromdb")
Elseif Request.QueryString("CustID") = "" Then  ' Add btn from MainMenu pg.
 ' Set var.
 Call SetVar("new")
End If

And the ClosePg(), DelRec(), SaveRec(), and SetVar() functions above are custom functions that would still need to be developed.
