11 mod_proxy changes for httpd 2.0.29-dev
12 *) don't do keepalives for sub-requests. [Ian Holsman]
14 *) fix up proxypass handling [Ian Holsman]
16 *) don't send If-Modified-Since, Cache-Control, or If-None-Match on
17 a subrequest [Ian Holsman]
19 mod_proxy changes for httpd 2.0.26-dev
20 *) Add New option 'HTTPProxyOverrideReturnedErrors'. By Turning the
21 Flag on, you will mask the error pages returned by the proxied
22 server, and will it will be handled as if your server generated
23 the error. This change was put in so that a 404 on a included
24 r-proxied component will act in the same manner as a 404 on a
25 included file. [Ian Holsman <ianh@cnet.com>]
27 mod_proxy changes for httpd 2.0.25-dev
29 *) Split proxy: space using <Proxy[Match] > directive blocks from
30 the <Directory[Match] > and <Files[Match] > blocks. Mod_proxy
31 now bypasses the directory and files testing phase (and skips
32 the http TRACE default handler on it's own, as well). Note that
33 <Location > blocks continue to be processed for proxy: requests.
34 [William Rowe <wrowe@covalent.net>]
36 *) apr_uri type/function namespace changes in apr_uri functions
37 [Doug MacEachern <dougm@covalent.net>]
39 mod_proxy changes for httpd 2.0.23-dev
41 *) break the proxy_http_handler into multiple smaller functions.
42 [John Barbee <barbee@veribox.net>]
44 *) Fix the proxy when the origin server sends back a 100
45 Continue response. [John Barbee <barbee@veribox.net>]
47 *) Change 'readbytes' from apr_size_t to apr_off_t due to change
48 in ap_get_brigade's parameters [John Barbee <barbee@veribox.net>]
50 mod_proxy changes for httpd 2.0.20-dev
51 *) Timeout added for backend connections.
52 [Victor Orlikowski <v.j.orlikowski@gte.net>]
54 *) Fix abort code path in proxy_http.c, similar to FTP fix.
55 [Chuck Murcko <chuck@topsail.org>]
57 *) Fix FTP ABOR command execution path.
58 [Victor Orlikowski <v.j.orlikowski@gte.net>]
60 *) FTP return code variable cleanup; fixed problem in login
61 [Chuck Murcko <chuck@topsail.org>]
63 *) Get PORT working again in the ftp proxy.
64 [Victor Orlikowski <v.j.orlikowski@gte.net>]
66 *) Return result code check for FTP QUIT, after fixing
67 problems with passive connection handling.
68 [Victor Orlikowski <v.j.orlikowski@gte.net>]
70 *) Reorganize ap_proxy_string_read() internally to not process eos
72 [Chuck Murcko <chuck@topsail.org>]
73 [Victor Orlikowski <v.j.orlikowski@gte.net>]
75 *) Remove result code check for FTP QUIT command. Some servers send
76 nothing at all back in response to QUIT.
77 [Chuck Murcko <chuck@topsail.org>]
78 [Victor Orlikowski <v.j.orlikowski@gte.net>]
80 mod_proxy changes for httpd 2.0.19
82 *) Reverse previous patch since the core reverted.
83 [Chuck Murcko <chuck@topsail.org>]
85 *) Remove indirection on number of bytes to read for input filters.
86 [Chuck Murcko <chuck@topsail.org>]
88 *) Fixed a problem with directory listing corruption in the
90 [Graham Leggett <minfrin@sharp.fm>]
92 *) mod_proxy and the proxy submodules now build properly as DSOs.
93 [Graham Leggett <minfrin@sharp.fm>]
95 *) Stopped the HTTP proxy from trying to read entity bodies when there
96 wasn't one (response was 1xx, 204, 205 or 304).
97 [Graham Leggett <minfrin@sharp.fm>]
99 *) Made sure dates were canonicalised correctly when passed to the client
100 browser through the HTTP proxy.
101 [Graham Leggett <minfrin@sharp.fm>]
103 *) Split each individual proxy protocol into separate modules.
104 [Graham Leggett <minfrin@sharp.fm>]
106 *) Added Max-Forwards support for all request types so as to prevent
108 [Graham Leggett <minfrin@sharp.fm>]
110 *) Fix warnings about byte count type on Darwin (connect handler).
111 [Chuck Murcko <chuck@topsail.org>]
113 mod_proxy changes for httpd 2.0.18
115 *) IPV6 EPSV support for IPV6 in FTP proxy.
116 [Graham Leggett <minfrin@sharp.fm>]
118 *) FTP directory filter works now.
119 [Graham Leggett <minfrin@sharp.fm>]
121 *) Fixed some thread-safety issues with the HTTP proxy in mod_proxy.
122 [Graham Leggett <minfrin@sharp.fm>]
124 *) PASV FTP works now.
125 [Graham Leggett <minfrin@sharp.fm>]
127 *) Reworked the line-at-a-time read from the control connection to
128 workaround a stray empty bucket returned by the HTTP_IN filter.
129 [Graham Leggett <minfrin@sharp.fm>]
131 *) Stopped the CORE filter from sending off an HTTP response when a
132 CONNECT tunnel was closed.
133 [Graham Leggett <minfrin@sharp.fm>]
135 *) Fixed the poll() loop in proxy_connect.c -> it works now!!!
136 [Graham Leggett <minfrin@sharp.fm>]
138 *) Converted send_dir() to ap_proxy_send_dir_filter() in proxy_ftp.c.
139 [Graham Leggett <minfrin@sharp.fm>]
141 mod_proxy changes for httpd 2.0.17
143 *) Major rework of ap_proxy_ftp_handler() to use filters (begone foul
144 BUFF!!!). It compiles, but is untested, and the build environment needs
145 to be fixed to include proxy_ftp.c.
146 [Graham Leggett <minfrin@sharp.fm>]
148 *) Cleanup of dead functions within proxy_util.c.
149 [Graham Leggett <minfrin@sharp.fm>]
151 *) Reworked the storage of the client socket between keepalive connections
152 to fix some nasty problems with the socket lasting longer than the
153 memory pool it was allocated from.
154 [Graham Leggett <minfrin@sharp.fm>]
156 *) Fixed bug where a hostname without a "." in it (such as "localhost")

167 moving some common code between http_handler and connect_handler
169 [Graham Leggett <minfrin@sharp.fm>]
171 *) Updated mod_proxy.html docs to include v2.0 configuration.
172 [Graham Leggett <minfrin@sharp.fm>]
174 *) Fixed problem where responses without entity bodies would cause
175 the directly following proxy keepalive request to fail.
176 [Graham Leggett <minfrin@sharp.fm>]
178 mod_proxy changes for httpd 2.0.15
180 *) Added support for downstream keepalives in mod_proxy.
181 [Graham Leggett <minfrin@sharp.fm>]
183 *) Changed mod_proxy ap_proxy_http_handler() to support APR properly.
184 [Graham Leggett <minfrin@sharp.fm>]
186 *) Fix problem where incoming response headers were not being returned
187 to the client in mod_proxy.
188 [Graham Leggett <minfrin@sharp.fm>]
190 *) Added X-Forwarded-For, X-Forwarded-Host and X-Forwarded-Server to
191 reverse proxied request headers in mod_proxy.
192 [Graham Leggett <minfrin@sharp.fm>]
194 *) replace INADDR_NONE with APR_INADDR_NONE [Ian Holsman <IanH@cnet.com>]
196 *) Fix problem with proxy configuration where globally set
197 configuration options were overridden inside virtual hosts.

200 *) Fix ProxyReceiveBufferSize where default value was left
202 [Graham Leggett <minfrin@sharp.fm>]
204 *) Some small changes:
205 - Ensured hop-by-hop headers were stripped as per
207 - Upgraded version code to HTTP/1.1.
208 - Added Connection: close until Keepalives come.
209 - Some cosmetic fixes and commenting.
210 [Graham Leggett <minfrin@sharp.fm>]
212 mod_proxy changes for httpd 2.0.14
214 *) removed ProxyNoCache and ProxyCacheForceCompletion config directives,
215 since we no longer directly cache from this module
216 [Chuck Murcko <chuck@topsail.org>]

221 *) initial rerebuild for 2.0
222 [Chuck Murcko <chuck@topsail.org>]
