2004-01-26Added reverse proxy support from Kim Holviala. His comments regardingRobert James Kaes10-31/+330
this addition follow: The patch implements a simple reverse proxy (with one funky extra feature). It has all the regular features: mapping remote servers to local namespace (ReversePath), disabling forward proxying (ReverseOnly) and HTTP redirect rewriting (ReverseBaseURL). The funky feature is this: You map Google to /google/ and the Google front page opens up fine. Type in stuff and click "Google Search" and you'll get an error from tinyproxy. Reason for this is that Google's form submits to "/search" which unfortunately bypasses our /google/ mapping (if they'd submit to "search" without the slash it would have worked ok). Turn on ReverseMagic and it starts working.... ReverseMagic "hijacks" one cookie which it sends to the client browser. This cookie contains the current reverse proxy path mapping (in the above case /google/) so that even if the site uses absolute links the reverse proxy still knows where to map the request. And yes, it works. No, I've never seen this done before - I couldn't find _any_ working OSS reverse proxies, and the commercial ones I've seen try to parse the page and fix all links (in the above case changing "/search" to "/google/search"). The problem with modifying the html is that it might not be parsable (very common) or it might be encoded so that the proxy can't read it (mod_gzip or likes). Hope you like that patch. One caveat - I haven't coded with C in like three years so my code might be a bit messy.... There shouldn't be any security problems thou, but you never know. I did all the stuff out of my memory without reading any RFC's, but I tested everything with Moz, Konq, IE6, Links and Lynx and they all worked fine.
2003-10-17Merged in changes from the 1.6.2 release. (Fixes for the filtering codeRobert James Kaes4-25/+47
and the HTML installation script.)

understandability of the documentation.
2003-08-07tinyproxy no longer includes a fall-back regular expression library,Robert James Kaes5-21/+11
so these files needed to be modified to only use the system's installed regular expression library.
2003-08-07Removed the included regular expression library, since it should comeRobert James Kaes3-6457/+0

2003-08-05Patch from Marc Silver to improve the readability and accuracy of theRobert James Kaes1-10/+10
tinyproxy man page.
2003-08-05# Fixed a comment to actually reflect what the function does.Robert James Kaes1-2/+2
2003-08-05Added the cookie header to the documented list of headers to allowRobert James Kaes1-0/+4
through.
2003-08-01Included patches from Steven Young to use the hashmap functionality toRobert James Kaes4-82/+64
manage the HTML error pages. It simplifies the source, and also make the object file smaller. Nice. Also added any casting from (void*) to ensure that the code compiles using a C++ compiler.
2003-07-31Added appropriate casts (void*) casts to allow the code to compileRobert James Kaes1-9/+12
cleanly using a C++ compiler. Changed the servers_waiting variable to an unsigned int, since the number of servers waiting can never be negative, and added an assert() to ensure this invariant.
2003-07-31(debugging_realloc): Removed the assert for the NULL pointer, sinceRobert James Kaes1-3/+2
realloc() can take a NULL pointer, as defined by the realloc() man page. Fixed the cast in both safefree() macros to compile cleaning using a C++ compiler.
2003-07-31Fixed the cast in both safefree() macros to compile cleaning using aRobert James Kaes1-3/+3
C++ compiler.

2003-07-31Added appropriate casts from (void*) so that the code will compileRobert James Kaes11-58/+67
cleanly with a C++ compiler. (Tested using GCC 3.3)
2003-07-24# Bumped up the version number because of a maintenance release (to fixRobert James Kaes1-2/+2
a problem with the scanner.c file.

2003-07-14# Bumped up version number.Robert James Kaes1-2/+2
2003-07-14(indicate_http_error): Added calls to va_end() before leaving theRobert James Kaes1-2/+6
function.
2003-06-26# Updated the ChangeLogRobert James Kaes1-0/+19
2003-06-26# Bumped up the version number and made sure to only add the debuggingRobert James Kaes1-3/+6
flags to flex if it really is flex.
2003-06-26# Removed the debugging information.Robert James Kaes1-8/+2
2003-06-26# Added debugging flags for the flex scanner.Robert James Kaes2-3/+5
2003-06-26(upstream_add): Rewrote the function to actually handle the variousRobert James Kaes1-33/+37
types of upstream configurations correctly. Hopefully, the code is also a little clearer in it's implementation.
2003-06-26# Removed the STRING_ADDRESS token since it was conflicting with theRobert James Kaes1-6/+4
IDENTIFIER directive and also the keyword directives.
2003-06-26Modified the patterns to allow the new upstream directives to work asRobert James Kaes1-9/+14
defined in the tinyproxy.conf documentation.
2003-06-26(debugging_free): Rather than assert on a NULL pointer, log the NULLRobert James Kaes1-4/+4
pointer and return.
2003-06-25# Bumped up the version number.Robert James Kaes1-2/+2
2003-06-25# Updated the changelogRobert James Kaes1-0/+7
2003-06-25Added a test to define INADDR_NONE if it's not present. For example,Robert James Kaes1-1/+8
SunOS (solaris 2.8) does not include this define. [Thank to Ben Hartshorne for pointing this out.]
2003-06-25Changed the calls to "ps" and "grep" to use a more portable syntax.Robert James Kaes1-1/+1
2003-06-23# Bumped up the version number.Robert James Kaes1-2/+2
2003-06-23# Added a bit more description to describe where to look for the errorRobert James Kaes1-1/+5
HTML files. In the future the installation script should modify the tinyproxy.conf file.
2003-06-20# Updated ChangeLogRobert James Kaes1-0/+39
2003-06-20Removed the "ViaHeader" directive and replaced it with theRobert James Kaes5-44/+47
"ViaProxyName" directive. The "Via" HTTP header is _required_ by the HTTP spec, so the code has been changed to always send the header. However, including the proxy's host name could be considered a security threat, so the "ViaProxyName" directive is used to set the token sent in the "Via" header. If the directive is not enabled the proxy's host name will be used.
2003-06-19# Removed the HTML error suggestion since it's been implemented withRobert James Kaes1-4/+5
Steven Young's patches. Added a suggestion for user authentication.
2003-06-06(connect_to_upstream): Fixed an off-by-one error in the snprintf()Robert James Kaes1-5/+6
call used to build the URL for the upstream proxy. [Patch suggested by David T. Pierso]
2003-06-02Remove the -O2 optimization if debugging is enabled. Also, remove theRobert James Kaes1-5/+9
-g option if the code does _not_ have debugging enabled.
2003-06-02Included additional examples of how to configure the upstream proxyRobert James Kaes1-10/+15
support for more selective proxying.
2003-06-02(upstream_get):Robert James Kaes2-38/+67
(upstream_add): Added support to allow ip addresses and networks to be used when matching an upstream proxy directive. [Code by Peter da Silva]
2003-05-31Changed the safefree() macro to make it safe to use a conditionalRobert James Kaes1-3/+11
statement, and also safe to use with a rvalue that has a side effect. [Bug fix recommended by Peter da Silva]
2003-05-31# Changed all the for calls to use the != test rather than < test.Robert James Kaes7-31/+31
The change was recommended in the C/C++ User Journal magazine.
2003-05-30# Updated ChangeLogRobert James Kaes1-0/+40
2003-05-30# Bumped up the version numberRobert James Kaes1-2/+2
2003-05-30# Changed the calls to vector_getentry() to use the new callingRobert James Kaes2-4/+5
convention.
2003-05-30(vector_getentry): Changed the API to return the data pointer and haveRobert James Kaes2-18/+19
the length returned in a argument variable pointer. This should be a more natural way of using the function.
2003-05-29# Added a vector_prepend() function and recoded the old vector_insert()Robert James Kaes2-15/+41
to be a general "insert" for both vector_append() and vector_prepend()
2003-05-29# Renamed the vector_insert() calls to vector_append()Robert James Kaes2-4/+4
2003-05-29(vector_append): Renamed the vector_insert() function to moreRobert James Kaes2-9/+9
accurately indicate that entries are appended to the end of the vector.
