Problem with url's that don't have the "=" sign

[msnews.microsoft.com]

Hi,

I am having a problem that the gateway I am working with removes the "="
sign from values in the postfield that are empty.
Example:
page.asp?aa=&ff=&xx=12
become:
page.asp?aa&ff&xx=12.
When I query the string and request the value of xx through IIS, it returns
nothing.
Can anyone help me finding where Microsoft defined the URL format that the
IIS (4.0) accepts?
I have already searched the RFC's.

why not:

a=request.querystring("a")
b=request.querystring("b")
if a<>"" then
qstr="a="&a
end if
if b<>"" then
if qstr<>"" then qstr=qstr&"&"
qstr=qstr&"b="&b
end if

response.redirect("somepage.asp?"&qstr)

Hello,

Thank you the post. As my understanding, you want to remove "=" in the
querystring if a item has null value. However, the "=" is necessary for an
item in the query string. If you don't want it, you compose a custom string
like Lasse suggest.

Hello,

After review your post again, I realize I may misunderstand the problem.
The query string has been changed by your gateway, and IIS can't handle it.
Is this correct?

Actually, the query string is not processed by IIS. This text is processed
by ISAPI filters, such as ASP or ASP.NET. In this problem, it is processed
by ASP.DLL.

Regarding the problem, if we can't change the setting of gateway, there are
two work around:

1. Before send request to IIS, we need to remove the unnecessary "=". For
example, from

page.asp?aa=&ff=&xx=12

to

page.asp?xx=12

2. Write IIS ISAPI filters which provide the capability of pre-processing
and post-processing of all data sent between the client and the server. For
more inforamtion, you may refer to following articles:
