2003-03-13# Changed calls to indicate_http_error() to use the new HTML variableRobert James Kaes1-34/+53
substitution mechanism. [Steven Young]
2003-01-28# (connect_to_upstream): Improved the preprocessor directives to makeRobert James Kaes1-3/+3
sure the function would compile cleanly regardless of how the directive was set.
2003-01-27(connect_to_upstream): Reorganized the preprocessor directives to makeRobert James Kaes1-3/+9
sure the function's symbol name is stored, even if upstream was not compiled it. This should keep some compilers from reporting errors.
2003-01-27(process_client_headers): Fixed inverted anonymous header logic. FixRobert James Kaes1-2/+2
comes from the FreeBSD port through James E. Flemer.
2002-12-04(strip_username_password): New function to remove anyRobert James Kaes1-1/+27
username/password part from the host URI. (extract_http_url), (extract_ssl_url): Use the new strip_username_password function to remove any non-host information from the URI.
2002-12-04Removed the "bool_t" type since it conflicts with the newer C standards.Robert James Kaes1-2/+2
The type was just replaced by "unsigned int" types.
2002-11-29(extract_http_url): Removed the leading "http://" from all the tests,Robert James Kaes1-11/+12
since it's skipped by the caller before the URL is passed to this function. (process_request): Include code to handle proxy FTP requests as well. This also lead to a bit of a cleanup in the calling conventions of extract_http_url function. tinyproxy can handle both types of resources by skipping the leading :// part.
2002-11-26Included code to disable the sending of the Via header. This is nowRobert James Kaes1-13/+18
controlled by the ViaHeader configure directive.
2002-11-13(relay_connection): Shutdown the client socket for writing once allRobert James Kaes1-1/+2
the data has been sent.
2002-11-03Removed all the code supporting the TCP tunnelling feature ofRobert James Kaes1-81/+1
tinyproxy. There is really no need for this code, since there are perfectly good programs out there (like rinetd) which are designed for TCP tunnelling. tinyproxy should be a good HTTP proxy, nothing more, and nothing less; therefore, the tunnelling code is gone.
2002-10-17(relay_connection): Ivan pointed out a bug with the code to send anyRobert James Kaes1-2/+2
remaining data to the server when the connections are being closed. It was a one line fix.
2002-06-06A bunch of changes from Petr Lampa that add transparent proxy support to ↵Robert James Kaes1-27/+98
tinyproxy. The additional code is in process_request(), but Petr also had to change around some of the other functions (like process_client_headers and handle_connection.) Note: Right now this code has not been tested, but it is believed to work. To enable run ./configure --enable-transparent-proxy
2002-05-31(process_server_headers): Since we're stripping off the carriage return and ↵Robert James Kaes1-2/+2
newline, we need to add them back on when sending the response header to the client.
2002-05-29(add_header_to_connection): Removed the "double_cgi" boolean, since ↵Robert James Kaes1-12/+5
tinyproxy now ignores all the headers after a "double CGI" situation has occurred. (get_all_headers): Instead of dropping duplicate headers when the "double CGI" situation occurs, tinyproxy will now drop _all_ the headers from the "inner" HTTP response.
2002-05-28(add_header_to_connection): Added a boolean to indicate that a "Double CGI" ↵Robert James Kaes1-6/+22
situation is in affect. This is needed to solve a problem with some sites (like cgi.ebay.com) where they are sending two HTTP response lines (and associated headers) with a response. (get_all_headers): Detect if a "Double CGI" situation has occured.
2002-05-28(get_all_headers): Added code to ignore a "response" line in a header. This ↵Robert James Kaes1-2/+31
was pointed out as being a problem with eBay (cgi.ebay.com) (process_server_headers): Added code to make skip blank lines before a response line.
2002-05-27(process_request): Changed the filtering code around to handle both domains ↵Robert James Kaes1-10/+21
and URLs.
2002-05-26Spelling changes (from thread to child.)Robert James Kaes1-2/+2
2002-05-24Fixed a tonne of spelling mistakes.Robert James Kaes1-5/+5
2002-05-23Fixed up a spelling mistake and changed various bits of code to takeRobert James Kaes1-9/+10
advantage of the fact that the peer's socket information is now stored inside the connection structure.
2002-05-17request->host might have been freed by the time we get toRobert James Kaes1-7/+3
free_request_struct(), so make sure it's pointing to memory.
2002-05-14Moved the definition of the struct buffer_s into the buffer.c file and outRobert James Kaes1-7/+7
of the buffer.h file. This also required the removal of the BUFFER_SIZE macro, and replace it with the buffer_size() function.
2002-05-08Removed the request logging in the tunnel because it breaks the tunnelRobert James Kaes1-1/+16
concept since it blocks waiting for information from the client before any data from the remote is relayed.
2002-04-28Added more error checking in process_client_headers() andRobert James Kaes1-34/+68
process_server_headers() functions. Also, better reporting of errors back to the client.
2002-04-26Changed the len type to ssize_t because we need to detect errors in theRobert James Kaes1-2/+2
recv() call. Thanks to Tom Cross for discovering this bug.
2002-04-26Need to check the return value of hashmap_first() since it could beRobert James Kaes1-24/+26
negative.
2002-04-25Check to see if request->path is actually allocated before trying to freeRobert James Kaes1-2/+8
it.
2002-04-25First change all the hashmap related calls to use the new API.Robert James Kaes1-47/+57
The remove_connection_headers() function now handles both the Connection header _and_ the Proxy-Connection header.
2002-04-24Fixed a couple of problems where tinyproxy was trying to free a memoryRobert James Kaes1-4/+7
block which had not been allocated. Also, the "proxy-connection" to the list of headers we don't pass.
2002-04-22Added the "Proxy-Connection" header to the list of client headers whichRobert James Kaes1-1/+2
are not passed along.
2002-04-18The stats now wait until after the client has finished sending all itsRobert James Kaes1-7/+11
headers before sending the HTTP response back. This should be more standards compliant.
2002-04-18Fixed a memory leak in reading in headers from the client or server.Robert James Kaes1-4/+12
2002-04-17If the initialize_conn() function fails, close the socket and return.Robert James Kaes1-3/+5
Also, changed the call to check_acl() to include the peer's IP and string addresses.
2002-04-16Various code clean up. There is nothing new here, just mechanical changesRobert James Kaes1-67/+43
to the source to either remove code which is not needed, or consolidate common code into a common section.
2002-04-15Changed the variable type in read_request_line() to an unsigned variableRobert James Kaes1-2/+2
in order to detect negative returns.
2002-04-15Changed the error boolean flag into a pointer to an error string and anRobert James Kaes1-16/+17
error code. We're storing this information because tinyproxy doesn't output the error information until _after_ the client has sent it's information.
2002-04-12Added code to support the new ConnectPort directive which is needed toRobert James Kaes1-1/+72
improve security of the tinyproxy system. This new directive allows the admin to block CONNECT methods to illegal ports.
2002-04-12Added a write_via_header() function which is now used in both headerRobert James Kaes1-40/+67
processing functions. Also, added a list of headers to drop in the process server header functions.
2002-04-11Did a bit of consolidation by moving code into remove_connection_headers()Robert James Kaes1-37/+106
and added the get_content_length() function. The process_server_headers() function was rewritten to remove the Connection header correctly, and also retrieve the Content-Length value. This value is needed in the relay_connection() function since there are some remote machines which do not properly close down the connection once the body has been retrieved. Thanks to James Flemer for finding a test case for this problem.
2002-04-09Removed the compare_header() function since it's been replaced by a callRobert James Kaes1-15/+7
the anonymous_search(). Added a few more log_message() calls to better explain error conditions. Fixed up a problem with X-Tinyproxy sending logic.
2002-04-07A _tonne_ of changes. It would almost be easier to just read the sourceRobert James Kaes1-163/+228
itself to find out all the changes. Changed the process_client_header() function to use the hashmap and vector modules. I've made this change to better handle the Connection header. The Connection header, it it's present, lists all the headers which should _not_ be transmitted any further along. An HTTP/1.1 proxy must respect this. Other changes are basically cosmetic.
2001-12-24Moved write_message() into sock.c because I'm using it in other places.Robert James Kaes1-53/+1
2001-12-23Cleaned up the code which sends the "Via" header. It now usesRobert James Kaes1-29/+24
write_message().
2001-12-20Created the CHECK_CRLF() macro to handle the tests for the appropriateRobert James Kaes1-6/+8
control characters in a string.
2001-12-19Removed duplicate code from process_server_headers() and removed the callsRobert James Kaes1-12/+9
to strlen(); readline() already returns the length of the string, so use that instead.
2001-12-19Damn---removed the debugging code from write_message().Robert James Kaes1-3/+1
2001-12-19Opps! Fixed a problem with negative numbers. :)Robert James Kaes1-3/+5
2001-12-19Redefined HTTP_LINE_LENGTH to be based on MAXBUFFSIZE (and set to aroundRobert James Kaes1-80/+118
16 KB.) Added the TUNNEL_CONFIGURED() macro to help with testing for the tunnel support code. Create the write_message() function to encapsulate the code which sends the information to the file descriptor. Moved the tunnel code into it's own function.
2001-12-18Updated the list of headers to ignore.Robert James Kaes1-3/+6
2001-12-17Added the code to log the request when in tunnelling mode.Robert James Kaes1-2/+22
