1bbf32f04c Fixed the problems with sending/not sending headers so that the CONNECT 
(SSL) method would work with upstream proxying!

3e91392c8a More changes to reqs.c and buffer.c 2001-10-25 04:42:32 +00:00

6afa56ba09 Changed the way relay_connection() works by having the both buffers 
emptied when either socket is closed. This should be better for the tunnel
connections.
Change the connect_to_upstream() function to better utilize the
establish_http_connection() function. Code re-use is cool. :)

f8d43bd423 Lowered the size of the read buffer to 2K since Ethernet seems to work 
with 1400 byte segments.

Robert James Kaes
a746b9d0b2 Moved the zero-length string setting to outside the tests in getpeer_*() 
functions. Also added a more robust error reporting for DNS errors.

Robert James Kaes
a6a026cb9e Changed the getpeer_*() functions to return the reason why the name or IP 
address could not be looked up.
 2001-10-22 16:52:34 +00:00

358b2781af Cleaned up the code in handle_connection() and added a NULL pointer test 
in the free request function.

ad743c1e41 Fixed a problem where a user's variable would be uninitialized if a DNS 
lookup failed.

b40e382e5a More moving around of the source code. Still can't get CONNECT to work 
with an upstream proxy.
 2001-10-19 18:03:49 +00:00
Robert James Kaes
26587ef1e7 Fixed a problem where a full buffer on the read side would cause the 
connection to be closed.

ac111ee8c6 Added netinet/in.h so that tinyproxy will compile on OpenBSD. 2001-10-18 03:44:06 +00:00

f869dfabdf More changes, mostly related to the support for an upstream proxy. 2001-09-16 20:15:06 +00:00
Robert James Kaes
6ab7ebcb31 send_http_message() doesn't create a memory block and store it in the 
connection's output_message variable. Instead the error is sent to the
client right away. Once we finish processing the client's headers it will
automatically accept the error message. So we get the same result, but
less memory is used.

606c8196a0 Added the configure variables to support the upstream proxy. 2001-09-16 20:12:29 +00:00

490754594e Added a check to make sure the Upstream and Tunnel directives are not both 
set in the configuration file.

b9c4c480d2 Moved the safe_write() and safe_read() functions here. 2001-09-16 20:11:07 +00:00
Robert James Kaes
08baf6b01b Moved the safe_read() and safe_write() functions into the sock.c file 
since they're now used in other places.

Added support for a true upstream proxy connection. This involved some
rewriting of the handle_connection() function and some of the support
functions so that they do perform the domain filtering and anonymous
filtering while still connecting to the upstream proxy. I think the code
should be cleaned up further.

a8f0272ace Added the token for Upstream and the code the handle the upstream 
directive in the configuration file.

Robert James Kaes
9860222979 Added the send_http_message() function to handle sending messages back to 
the client. It's used by httperr() and showstats().
 2001-09-15 21:29:59 +00:00

d3213f193c Changed to rotating the log file instead of truncating it. Also using the 
create_file_safely() function to eliminate potential security problems.

7615024f27 Changed to using the send_http_message() function so that the HTTP headers 
are sent properly.

ea4d707d12 Finally got the SSL problem fixed. We can not send _any_ client headers 
(including the new line) to the origin server when in tunnelling mode. SSL
now works correctly. Yeah.
 2001-09-14 21:16:56 +00:00
Robert James Kaes
9c520c7a50 Changed the buffer pointer in safe_write() to be const void* since we're 
not changing the values.

Instead of building a new request and memory, simply send each part
separately. Actually uses less memory _and_ less code.
