Hi All.
We desire to set up file upload/download feature with a HTTP-Web-Server where the client runs in an embedded-environment, and thus wish to achieve this using the absolute basic primitives - socket programming (on the client-side that is).
We have been able to achieve the download functionality.
For brevity, this is how we do it ::
##################################################################
telnet localhost 80Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
GET /1/test_download_file.txt HTTP/1.0\r\n\r\nHTTP/1.1 200 OK
Date: Sun, 09 Aug 2015 16:50:54 GMT
Server: Apache/2.4.7 (Ubuntu)

Content-Length: 29
Connection: close
Content-Type: text/plain
Testing download success !!!
Connection closed by foreign host.

We tested our code on a local HTTP-server, and the same code is serving us well with the production HTTP-server.
When we try the same for file-uploading, this is what we get ::
##################################################################
telnet localhost 80Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

Following is the Virtual-Host configuration ::
##################################################################
<VirtualHost *:80>
# The ServerName directive sets the request scheme, hostname and port that
# the server uses to identify itself. This is used when creating
# redirection URLs. In the context of virtual hosts, the ServerName
# specifies what hostname must appear in the request's Host: header to
# match this virtual host. For the default virtual host (this file) this
# value is not decisive as it is used as a last resort host regardless.
# However, you must set it for any further virtual host explicitly.
#ServerName
www.example.com ServerAdmin webmaster@localhost
DocumentRoot /var/www/html
# Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
# error, crit, alert, emerg.
# It is also possible to configure the loglevel for particular
# modules, e.g.
#LogLevel info ssl:warn
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
<Directory />
AllowOverride All
<Limit GET HEAD POST PUT DELETE OPTIONS>
Order Allow,Deny
Allow from all
</Limit>
</Directory>
# For most configuration files from conf-available/, which are
# enabled or disabled at a global level, it is possible to
# include a line for only one particular virtual host. For example the
# following line enables the CGI configuration for this host only
# after it has been globally disabled with "a2disconf".
#Include conf-available/serve-cgi-bin.conf
</VirtualHost>

Please note that in the test-environment, the http-server is running on Ubuntu 14.04 on a 32-bit machine desktop.
(Just to re-iterate, the file-download works using the absolute basics, but the file-upload does not).
I have tried googling and tried whatever it threw us, but I am unable to make the file-upload work.
