application/x-www-form-urlencoded and multipart/form-data forms?

How to handle several types of source form encoding using HugeASP upload and ASPForm object.

Q: I am writing in reference to your Huge-ASP upload software product. I have seen in several places in the help file that this software can handle multipart/form-data encoded forms AND application/x-www-form-urlencoded forms. I don't see any example in the help files of an application/x-www-form-urlencoded form being processed. Please advise as to whether this is possible, and please provide an example. Thanks for your time and attention.

Huge-ASP upload can accept both application/x-www-form-urlencoded and multipart/form-data forms. You do not need to do some special settings to accept these two kinds of form. ScriptUtils.ASPForm component contains next simple code in ScriptUtils.ASPForm.Read method (in C++, of course):

Dim ContentType
ContentType = LCase(Request.ServerVariables("HTTP_CONTENT_TYPE"))
If Left(ContentType,19) = "multipart/form-data" Then
  'Multipart source form
  ProcessMultipartData
ElseIf ContentType = "application/x-www-form-urlencoded" Then
  'URLEncoded source form
  ProcessURLEncodedData
Else
  'Unknown content-type
  m_FormType = ftNone  
End If

There is a special property ScriptUtils.FormParser.FormType which gives you info what type of form is currently processed. You can use both

<Form Action=hugeupload.asp method="POST">
 <Input Name=Description>
 <Input Type=Submit>
</Form>

<Form Action=hugeupload.asp method="POST" ENCTYPE="multipart/form-data">
 <Input Name=Description>
 <Input Type=Submit>
</Form>

And then you can accept source field in server-side ASP by the same ASP code:

'Create form object
Dim Form
Set Form = Server.CreateObject("ScriptUtils.ASPForm")

Dim Description
Description = Form("Description")
