I have tested TIdHTTPProxyServer from indy-10  library but it is
consume 100% cpu
I did not find enough information to create a ProxyServer (inet
+Synapse)


I need a way to Read all requests from Browsers (Capture files private
extensions)

                              server
                                  |         
                                  |
                       local proxy server
                           /               \      
        pdf.zip..     /                  \  html.php...
                        /                     \      
          download                   Browsers
          manager

I have found an example from synapse


http://www.openlcb.org/trunk/scratchpads/jkueneman/Components/synapse4
0/source/demo/httpproxy/ProxyThrd.pas


Everything works well ..But
The example does not deal with FTP protocol +


I want the browser use proxy at the same port (FTP and HTTp) .
I do not want you writing code example. i need Only a simple
information


Suggestions

- Make a FTP proxy inside synapse example
- Redirection raw TCP data if  browser request a FTP link
- Changing http header When answering and demand to browser To ignore
the proxy <- possible

What is the right proposal and whether there are others

You simply can't do that very easily. You need to 2 ports, one for (s)
ftp one for http(s). Or you have to device a way that the proxy
accepts just raw data, analyzes it for protocol and forward it to the
correct server port.

It is simply a bad idea and against all specifications to have two
protocols running on the same port.

You may be interested in tunneling ftp over http. Not for the
fainthearted
