RE: Processing an HTTP Post (not form)

Ben,

What type of data is the applet posting? Can you tell why it is posting it
using the application/octet-stream content type? This content type is more
commonly used to transport files.

Subject: Processing an HTTP Post (not form)


I have a java applet that posting some data to my cold fusion template.  But
I can't seem to access the data.  It doesn't appear to be showing up in a
FORM post, more of a raw-socket post as far as I can tell from the
documentation. When I output the CGI structure seen by the webserver via the
Cold Fusion Template, I get the list attached at the bottom.

As you can see, 46K of some data is being detected but I don't know how to
access this data.  I also notice the request method is now set to POST
instead of GET.  Even though I loop from the form structure and the variable
fieldnames it doesn't see any named variables.  The java applet also has the
ability to transmit a header before the post, is there a way I can fake a
form header so this data does show up as a form field?

HTTP_CONTENT_LENGTH - 46840
HTTP_CONTENT_TYPE - application/octet-stream

These CGI variables show the 46K of data coming through...

Any ideas?

INSTRUCTIONS ON THE POST FORMAT:
==
this is the format of POST Data

P(1Byte Character)
Length of The header for CGI author(8byte Characters)
The header for CGI author
Length of Image(8byte Characters)
\r\n(CR LF)
Image data(format is PNG or JPEG)
Length of thumbnail(8byte Characters)
thumbnail(format is PING or JPEG or AnimationData)
Length of thumbnail2(8byte Characters)
thumbnail(format is PING or JPEG or AnimationData )

Length is not transmitted, either, when there is not thumbnail.

format of poo=true
0x
\r\n(CR LF)
Image data(format is PNG or JPEG)
Lnegth of thumbnaill(8byte characters)
thumbnail(format is PING or JPEG or AnimationData)

If you're using CF 5, you can use the GetHTTPRequestData function to
retrieve the raw HTTP request body, which is what you want. If not, there's
no way of which I'm aware within CF to get the request body directly.

If you can change what the Java applet sends, you might be able to simply
add something like this at the very beginning of your HTTP request body:

myvar=

Then, everything else within the body will be in the variable Form.myvar
within your CF action page. This assumes that the Java applet is posting
with the standard POST MIME type of application/x-www-form-urlencoded; if
it's formatting the data some other way, you might have problems.
