11mod_proxy changes for httpd 2.0.29-dev
12  *) don't do keepalives for sub-requests. [Ian Holsman]
13  
14  *) fix up proxypass handling [Ian Holsman]
15
16  *) don't send If-Modified-Since, Cache-Control, or If-None-Match on 
17     a subrequest [Ian Holsman]
18
19mod_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>]
26
27mod_proxy changes for httpd 2.0.25-dev
28
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>]
35
36  *) apr_uri type/function namespace changes in apr_uri functions
37     [Doug MacEachern <dougm@covalent.net>]
38
39mod_proxy changes for httpd 2.0.23-dev
40
41  *) break the proxy_http_handler into multiple smaller functions.
42     [John Barbee <barbee@veribox.net>]
43
44  *) Fix the proxy when the origin server sends back a 100
45     Continue response.  [John Barbee <barbee@veribox.net>]
46
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>]
49
50mod_proxy changes for httpd 2.0.20-dev
51  *) Timeout added for backend connections.
52     [Victor Orlikowski <v.j.orlikowski@gte.net>]
53
54  *) Fix abort code path in proxy_http.c, similar to FTP fix.
55     [Chuck Murcko <chuck@topsail.org>]
56
57  *) Fix FTP ABOR command execution path.
58     [Victor Orlikowski <v.j.orlikowski@gte.net>]
59
60  *) FTP return code variable cleanup; fixed problem in login
61     [Chuck Murcko <chuck@topsail.org>]
62
63  *) Get PORT working again in the ftp proxy.
64     [Victor Orlikowski <v.j.orlikowski@gte.net>]
65
66  *) Return result code check for FTP QUIT, after fixing
67     problems with passive connection handling.
68     [Victor Orlikowski <v.j.orlikowski@gte.net>]
69
70  *) Reorganize ap_proxy_string_read() internally to not process eos
71     buckets.
72     [Chuck Murcko <chuck@topsail.org>]
73     [Victor Orlikowski <v.j.orlikowski@gte.net>]
74
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>]
79

81
82  *) Reverse previous patch since the core reverted.
83     [Chuck Murcko <chuck@topsail.org>]
84
85  *) Remove indirection on number of bytes to read for input filters.
86     [Chuck Murcko <chuck@topsail.org>]
87
88  *) Fixed a problem with directory listing corruption in the
89     PROXY_DIR filter.
90     [Graham Leggett <minfrin@sharp.fm>]
91
92  *) mod_proxy and the proxy submodules now build properly as DSOs.
93     [Graham Leggett <minfrin@sharp.fm>]
94
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>]
98
99  *) Made sure dates were canonicalised correctly when passed to the client
100     browser through the HTTP proxy.
101     [Graham Leggett <minfrin@sharp.fm>]
102
103  *) Split each individual proxy protocol into separate modules.
104     [Graham Leggett <minfrin@sharp.fm>]
105
106  *) Added Max-Forwards support for all request types so as to prevent
107     loops.
108     [Graham Leggett <minfrin@sharp.fm>]
109
110  *) Fix warnings about byte count type on Darwin (connect handler).
111     [Chuck Murcko <chuck@topsail.org>]
112
113mod_proxy changes for httpd 2.0.18

115  *) IPV6 EPSV support for IPV6 in FTP proxy.
116     [Graham Leggett <minfrin@sharp.fm>]
117
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>]
123
124  *) PASV FTP works now.
125     [Graham Leggett <minfrin@sharp.fm>]
126

128     workaround a stray empty bucket returned by the HTTP_IN filter.
129     [Graham Leggett <minfrin@sharp.fm>]
130
131  *) Stopped the CORE filter from sending off an HTTP response when a
132     CONNECT tunnel was closed.
133     [Graham Leggett <minfrin@sharp.fm>]
134
135  *) Fixed the poll() loop in proxy_connect.c -> it works now!!!
136     [Graham Leggett <minfrin@sharp.fm>]
137
138  *) Converted send_dir() to ap_proxy_send_dir_filter() in proxy_ftp.c.
139     [Graham Leggett <minfrin@sharp.fm>]
140
141mod_proxy changes for httpd 2.0.17
142
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>]
147
148  *) Cleanup of dead functions within proxy_util.c.
149     [Graham Leggett <minfrin@sharp.fm>]
150
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>]
155
156  *) Fixed bug where a hostname without a "." in it (such as "localhost")
157     would not trigger an IP address check with ProxyBlock.
158     [Graham Leggett <minfrin@sharp.fm>]
159
160mod_proxy changes for httpd 2.0.16
161
162  *) Fixed ProxyBlock bugs with ap_proxy_http_handler() and
163     ap_proxy_connect_handler().
164     [Graham Leggett <minfrin@sharp.fm>]
165
166  *) Updated ap_proxy_connect_handler() to support APR, while
167     moving some common code between http_handler and connect_handler
168     to proxy_util.c.
169     [Graham Leggett <minfrin@sharp.fm>]
170
171  *) Updated mod_proxy.html docs to include v2.0 configuration.
172     [Graham Leggett <minfrin@sharp.fm>]
173
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>]
177
178mod_proxy changes for httpd 2.0.15
179
180  *) Added support for downstream keepalives in mod_proxy.
181     [Graham Leggett <minfrin@sharp.fm>]
182
183  *) Changed mod_proxy ap_proxy_http_handler() to support APR properly.
184     [Graham Leggett <minfrin@sharp.fm>]
185
186  *) Fix problem where incoming response headers were not being returned
187     to the client in mod_proxy.
188     [Graham Leggett <minfrin@sharp.fm>]
189
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>]
193
194  *) replace INADDR_NONE with APR_INADDR_NONE [Ian Holsman <IanH@cnet.com>]
195
196  *) Fix problem with proxy configuration where globally set
197     configuration options were overridden inside virtual hosts.
198     [Graham Leggett <minfrin@sharp.fm>]
199
200  *) Fix ProxyReceiveBufferSize where default value was left
201     uninitialised.
202     [Graham Leggett <minfrin@sharp.fm>]
203
204  *) Some small changes:
205     - Ensured hop-by-hop headers were stripped as per
206       RFC2616 13.5.1.

211
212mod_proxy changes for httpd 2.0.14
213
214  *) removed ProxyNoCache and ProxyCacheForceCompletion config directives,
215     since we no longer directly cache from this module

217
218  *) removed cache
219     [Chuck Murcko <chuck@topsail.org>]
