GET and form data

[Jonathan Allen]

I have this code...

If Request.Form("Name") = "" Then
Response.Redirect "error.asp"
End if

If the browser does a GET against this page, sometimes the Response.Redirect
doesn't happen. It is as if there is form data being sent on a GET.

Has anyone seen this before?

You need to use Request.Querystring for GET requests...... and Request.Form for POST requests.

If Request.Form("Name") = "" AND Request.Querystring("Name") = "" Then
Response.Redirect "error.asp"
End if

Yes, we all know what SHOULD be happening. But in reality, something strange
is going on.

Is there any combination of browser, OS, phase of the moon, that would cause
a GET request to have form data? Or at least make IIS think there is form
data?

I think:

Response redirect gives a header request to the browser to redirect.
so the GET is browser dependent.

Could you try a GET of:

application("noformname")="no"
If Request.Form("Name") = "" Then
application("noformname")="yes"
End if

[and thest for that application variable in another asp-file]

and seperate a GET of just:

Response.Redirect "error.asp"

True, but it looks like my users are using Win95/98 and IE. Also, a
Response.Redirect halts the execution of the script, so there shouldn't be
any way to continue even if the browser gets confused.

Since Request.Form("Name") is an OBJECT with properties other than string
values, I am never surprised to see "unexpected" behavior when comparing it
to a string. Alternatives to consider:

• If Request.Form("Name").Count = 0 Then...
• If Request.Form("Name").Item = "" Then...
• If Request.Form("Name").Item = "" And
Request.QueryString("Name").Item = "" Then...
