Extra Path Info

C

cdkorzen

I'm sorry if this is a rehash, but all I see is the same info.

Here's my debacle:

I CAN get the PATH_INFO to work. With ANYTHING but ASP. Python, Perl,
Cmd files... works fine. ASP can't find a file when extra path
information is added. Is there a switch in ASP or something I can
change that'll get it to work?

Thanks!

Sorry it's not too clear.

Here's my issue: I'm using VBScript in ASP, and Python to create a
CGI.

Python Code:
=============================================
import os

print "Content-type: text/plain\n"

print "Path info:", os.environ["PATH_INFO"]
=============================================

ASP:
=============================================
<%@ Language=VBScript %>
<HTML>
<HEAD>
<meta name="vs_targetSchema"
content="http://schemas.microsoft.com/intellisense/ie3-2nav3-0">
<TITLE>Path Info Test</TITLE>
</HEAD>
<body>
The extra path information is: <%=
Request.ServerVariables("PATH_INFO") %>
</body>
</HTML>
=============================================


My issue is, when I call them as:
http://<my server>/<path>/<filename>
both scripts return the PATH_INFO as /<path>/<filename>

When I call them as:
http://<my server>/<path>/<filename>/<extra>/<path>
the Python script returns a PATH_INFO of
/<path>/<filename>/<extra>/<path>
and the server reports that the ASP file cannot be found.

I have made sure that in the application settings, "Check to make sure
this file exists" is disabled.

So, my question is why do the two scripts react differently to added
path information? My initial guess was that the Python script calls
the EXE and runs like a CGI but the ASP runs as an ISAPI, but that
didn't make much sense to me.

Hope this clarifies my question.

ASP has no concept of "extra path info", unless you are talking about
querystrings. In IIS, the only thing allowed after the file name is a
list of name/value pairs initiated with a question mark and delimited
with &'s:

http://www.myweb.com/path/abc.asp?a=526&b=hello

This name/value pair list is called a querystring. Is that what you are
talking about? I'm really not familiar with Python.

Sorry it's not too clear.

nope, still dont know what you mean. But

maybe this line may clear things up

<%= Server.MapPath( Request.ServerVariables("PATH_INFO")) & "?" &
Request.ServerVariables("QUERY_STRING") %>


or this one

http:// <%=Request.ServerVariables("LOCAL_ADDR") &
Request.ServerVariables("URL") & "?" &
Request.ServerVariables("QUERY_STRING") %>

I take issue with your assertion that in IIS, the only thing allowed
after the filename is the query string. It definitely will allow such
data, as evidenced by the Python code. Also, look for servers that use
it, as an example:

http://<someserver>/news/data.dll/articles/1304?printview=true

I don't know if something exactly like that exists, but I've seen
similar... the extra path information is used to make the site
search-engine friendly, since search engines usually ignore query
strings.

The Python code is acting similar to a CGI, and in the Application
settings I have the set up the mapping, so that the Python interpreter
is called and acts similar to a CGI program, as far as I understand.

Ah! I did not realize you were talking about browsing to a dll (note

Someone else will need to step in on this. I have no experience in this

Let me make it even more clear:

Create an ASP.NET web application with C#

Add a label to the page

Add this code to the Page_Load event:
==================================
Label1.Text = Request.PathInfo;
==================================

Now, browse to the page like normal. Nothing appears.

Go to the page, but after typing the name of the page /<filename>.aspx,
type in /test so it looks like /<filename>.aspx/test

The label will say /test

THAT is the effect I'm trying to achieve, but with ASP. I'm hoping to
do a prototype with ASP to get the UI and an idea of the flow, then
move to something like CGI, ASP.NET or ISAPI.

A clunky way to do this is to make the page the 404 custom error handler for
itself.
However the extra info would need to be found from the QUERY_STRING server
variable instead. One problem might be that relative paths won't work well
like this.

A slightly less clunky way is to drop the .asp from filename and make a
folder with the filename. Now add the file as a custom 404 handler for that
folder. The URL paths are preserved from the browsers point of view so
relative paths will work. You still need to parse out of the QUERY_STRING
the info you need.
