New to Cache and CSP,

Hacking up Sample upload.csp and was wondering if you can get the drive letter and director (on a Windows system) on the file that is picked?

I cannot find anything on MIMEDATA, such as FileName, Size, MemSection, etc that can do this.

Another meothod that can accomplish this?

In HTML world, we have two sides. Server and Browser. Upload means that some users far from our server can choose the file on their machines and upload it to the server through the network. The server will get full this file and only filename. You can't get file path because it is useless to you. If you would run this file in a browser and try to choose any your local file then push upload file button. You will get some information about this file, like for me.

Doubtful. Web browsers security policies probably forbid this kind of thing.

Why do you need that?

Dmitry,

Thanks for the response and I totally understand this answer.

So then, based on the Samples upload.csp, once the file is picked, how would you write this to a Cache database?

I've already written a Cache class that will read in a file and create a database. I used %Stream.FileCharacter to accomplish this.

I'm not clear how I can do this within a csp and what is provded in the upload sample.

the code is already included in the CSP example
the file comes a MIME data in %request:

for easier reading compile the CSP file and see the generated class csp.upload.cls in SAMPLES

<csp:if condition='($data(%request.MimeData("FileStream",1)))'>
<hr> 
Submitted filename: #(..EscapeHTML(%request.MimeData("FileStream",1).FileName))# 
Size of file: #(..EscapeHTML(%request.MimeData("FileStream",1).Size))# 
Mime Section: #(..EscapeHTML(%request.MimeData("FileStream",1).MimeSection))# 
Type of stream: #(..EscapeHTML($classname(%request.MimeData("FileStream",1))))# 
Content Type: #(..EscapeHTML(%request.MimeData("FileStream",1).ContentType))# 
 
First 200 characters of stream: 
<ul>
<script language="Cache" runat="server">
