Your response

Hi Henerik,

        Thanks for your quick response to my mail. I have been trying to move 
forward with your suggestions and as yet not have been able to come up with a 
solution. In order to make things more clear I have below included an example of
what I am trying to do. I would appreciate if you could help me out.

 First of all I used the command line on my terminal to connect and download 
from a server using the POST method. The results are shown in a). below. After 
that I tried to use your tool (w3c) to perform the same operation. This is shown
in b). below.

The results of the w3c command are:

Read (100% of 1k)
Written(266% of 1k)
Written(100% of 1k)
Finished.

The result is I did not receive any document. If the program gets the document 
where does it put it ?

In any case could you please tell me what am I doing wrong? I expect to fetch 
some document as a result of the w3c command. 

Also, how should I send the Content-type, Content-length and the query string? I
also tried adding content-type and Content-length headers to the file 
"query.txt".

Thanks again for your time and effort.

Best Regards;


Poonam Mehtani.

<BLOCKQUOTE><B>Abstract: </B>We present a framework for 3--D surface 
reconstruction that can be used to model fully 3--Dimensional scenes from an 
arbitrary number of stereo views taken from vastly different viewpoints. This is
a key step toward producing 3--D world-descriptions of complex scenes using 
stereo and is a very challenging problem: real-world scenes tend to contain many
3--D objects, they do not usually conform to the 2-1/2--D assumption made by 
traditional algorithms, and one cannot take it for granted that the computed 
3--D points can easily be clustered into separate groups. Furthermore, stereo 
data is often incomplete and sometimes erroneous,!
 which makes the problem even m

     Input Session
     -------------
     
     I tried the following using Command Line Tool to retrieve the above 
     document:
     
w3c -post query.txt -dest http://www.ai.sri.com/pubs/glimpse_to_html.pl
     
where the file query.txt contains the query string: 
"field_name=Year&pattern=1996".
     
     
     Results of the w3c command
