mod_proxy_ajp: Forward SSL_PROTOCOL. Forthcoming versions of Tomcat know how to extract the information and provide it as a request attribute. Compatibility is not broken, because we forward it as a named request attribute, not with a new byte encoded name.

Forward local IP address as a custom request attribute like we already do for the remote port. Both were forgotten in the original AJP 13 spec but are needed by the Servlet spec. Until now, Tomcat simply returns for getLocalAddr() the same as for getLocalName(). The next round of Tomcat releases will look for the optional new request attribute. See also Tomcat BZ 56661.

mod_proxy_ajp: Support unknown HTTP methods. BZ 54416 Forward unknown methods as request attributes using method id SC_M_JK_STORED=0xFF and request attribute id SC_A_STORED_METHOD=13. Code ported from mod_jk (which got it from mod_jk2). Supported by Tomcat at least since TC 4.1. Doesn't seem to be supported by Jetty though.

fix some comments

Fix some typos

Further clarify the naming of the entity that originates the request by calling that entity a useragent instead of a client.

Add lots of unique tags to error log messages

Introduce a per connection "peer_ip" and a per request "client_ip" to distinguish between the raw IP address of the connection and the effective IP address of the request.

Introduce a per request version of the remote IP address, which can be optionally modified by a module when the effective IP of the client is not the same as the real IP of the client (such as a load balancer).

check return status

More ap_log_rerror() usage and axe some more AJP: prefixes

Improve logging for mod_proxy_ajp.

Make AJP trace messages a bit less cryptic.

Move some debug log statements to trace level and improve message format consistency.

mod_proxy_ajp: Respect "reuse" flag in END_REPONSE packets.

Use the new APLOG_USE_MODULE/AP_DECLARE_MODULE macros everywhere to take advantage of per-module loglevels

The remote port information was forgotten from the builtin data of the AJP 13 protocol. Since the servlet spec allows to retrieve it via getRemotePort(), we provide the port to the Tomcat connector as an additional request attribute. Modern/future Tomcat versions know how to retrieve the remote port from the attribute AJP_REMOTE_PORT.

* save_table needs to be declared first before it can be used.

AJP was dropping pre-existing cookies. Use same logic as HTTP to tuck them away

Make AJP HEAD aware

Here too, the limited comparison ignored the trailing NIL character

Convert just the message text to EBCDIC, and not the (already EBCDIC) status code

At support for ProxyIOBufferSize in AJP.

Revert 451953 and 451951. Log the real r->method that is unsupported by the AJP protocol.

Ups. Fix typo. We are logging int, not string.

If the r->method_number is unknown the r->method is unknown or corrupted as well. Log the method number that was not recognized.

Fix compile time warning. AJP protocol method is byte.

update license header text

small cleanup of EBCDIC support in mod_proxy_ajp

Update the copyright year in all .c, .h and .xml files

* Crosscheck the length of the body chunk with the length of the ajp message to prevent readings beyond the buffer boundaries which possibly could reveal sensitive memory contents to the client.

* Fix PR38340 by actual getting the word and thus advancing the message buffer pointer to the next data. Submitted by: Aleksey Pesternikov <apesternikov yahoo.com> Reviewed by: Ruediger Pluem

Fix Cookie2 header problems that originates back from mod_jk. Cookie2 was always sent as Cookie.

In Apache-2.x, the function is called apr_pstrdup(). The 'tmp' variable is not really necessary.

Sorry, previous commit was not ok.

The string comming from TC is in ASCII and the string returned by apr_psprintf isn't.

No functional Change: Removing trailing whitespace. This also means that "blank" lines consisting of just spaces or tabs are now really blank lines

* Fix PR37100 (SEGV in mod_proxy_ajp), by sending the data up the filter chain immediately instead of spooling it completely before passing it to the filter chain. It contains a bandaid to handle intentional flushes from Tomcat side.

Fix mess left by incompleteness of previous ProxyPassReverse fix

Use two optional functions from mod_ssl so that we can receive both is_ssl and ssl_var for ajp protocol. This is combined work based on patch from Brad Boyer and Joe Orton's suggestion to use ssl_var_lookup.

Return 'real' error status codes instead APR_EGENERAL. The return status code will be used to determine wether the message is invalid or the remote host failed processing the request. This is needed to mark the worker as in error state in case it is member of load balancer.

Update copyright year to 2005 and standardize on current copyright owner line.

Also translate Destination headers when ProxyPassReverse'd * modules\proxy\mod_proxy_http.c (process_proxy_header): reverse map Destination header. NOTE: This is some darn nasty looking code... * modules\proxy\ajp_header.c (ajp_unmarshal_response): reverse map Destination header.

Match parameter types

Rewrite Cookies and other headers in mod_proxy_ajp as configured with ProxyPassReverse and ProxyPassReverseCookiePath. * modules/proxy/proxy_ajp.c (ap_proxy_ajp_request): Update call to ajp_parse_header(). * modules/proxy/ajp.h (ajp_msg_get_string): constify argument. (ajp_parse_header): Add conf argument. * modules/proxy/proxy_util.c (ap_proxy_location_reverse_map): Promoted from mod_proxy_http. (ap_proxy_cookie_reverse_map): Promoted from mod_proxy_http; renamed from proxy_cookie_reverse_map. * modules/proxy/ajp_msg.c (ajp_msg_get_string): constify argument. * modules/proxy/proxy_http.c (ap_proxy_location_reverse_map, proxy_cookie_reverse_map: Removed. (process_proxy_header): Update header mapping table to reference the now public functions. * modules/proxy/ajp_header.c (ajp_unmarshal_response): And conf argument. Reverse map cookies and other headers. (ajp_parse_header): Update call to ajp_unmarshal_response(). * modules/proxy/mod_proxy.h (ap_proxy_location_reverse_map, ap_proxy_cookie_reverse_map): Declare functions that have been promoted to be public. (ap_proxy_header_reverse_map_fn): Typedef for the signature of the above two functions (currently used in mod_proxy_http).

Make the combination of mod_proxy_ajp and mod_rewrite work correctly. * modules/proxy/proxy_ajp.c (ap_proxy_ajp_request): Update call to ajp_send_header(). * modules/proxy/ajp.h (ajp_send_header): Add a uri parameter. * modules/proxy/ajp_header.c (ajp_marshal_into_msgb): Add a uri parameter and use the passed in uri instead of r->uri. (ajp_send_header): Add a uri parameter. Update call to ajp_marshal_into_msgb(). * modules/mappers/mod_rewrite.c (is_absolute_uri): Add handling of 'ajp' and 'balancer' schemes.

Remove duplicate logging from alloc and send data_msg. The logging is already done in the proxy_ajp. Also remove unused function params.

Remove logging inside ajp_send_data_msg. If send fails it is logged inside proxy_ajp with the same message.

Fix format string warnings in proxy_ajp on 64-bit platforms: * modules/proxy/ajp_header.c (ajp_send_data_msg): Use APR_SIZE_T_FMT. * modules/proxy/ajp_link.c (ajp_ilink_receive): Don't pass \n to ap_log_error; do use APR_SIZE_T_FMT. * modules/proxy/ajp_msg.c (ajp_msg_dump, ajp_msg_check_header, ajp_msg_copy): Use APR_SIZE_T_FMT. (ajp_log_overflow): New function. (ajp_msg_{append,peek,get}_*): Use it. * modules/proxy/proxy_ajp.c (ap_proxy_ajp_request): Use APR_SIZE_T_FMT.

Added SSL custom indicators. They can be set using SetEnv directive, so we don't need an extra one like the JkEnvVar is in the mod_jk.

Implement REQ_ATTRIBUTE using request rec environment table, so we can use standard SetEnv directive for that. The ajp specific attributes has to be prefixed using 'AJP_', and are passed withouth that prefix to the backend.

Use the session route from request rec notes.
