I'm getting an error:" http headers already written", when I redirect
back the page I came from.
I writing an on-line store app. The page 1 lists products, desc,
price in a table. Click on a product, it adds it to an XML shopping
bag and , thru a link, jumps to page2 that prints everyhing in the bag
so far. At the bottom of page2 is a TYPE SUBMIT button that takes you
back to page 1 for more shopping. The form for the button uses
Response.Write "<FORM METHOD=""POST"" ACTION="""
Response.Write Request.ServerVariables("SCRIPT_NAME") & """>"
....
Response.Write "<INPUT TYPE=SUBMIT NAME=""DO"" VALUE=""Shop
for more""> "
to post the button data back to itself. The following checks if the
button was pushed and redirects to page1 if it was:
If Request.ServerVariables("CONTENT_LENGTH")>0 Then
Select Case Trim(Request.Form("DO"))
Case "Shop for more"
Response.Redirect "page1.asp"
Response.End
....
End Select
End If
Problem is, when I click the bi\utton, the error about headers already
written comes up.
I think it's because HTML commands have been written before the
redirct, but I don't know how to work around it.
Any help? 2 1375 http://www.aspfaq.com/2011 http://www.aspfaq.com/2217
