<h3>3proxy PCRE (Perl Compatible Regular Expressions) Filtering</h3>
<p><b>Note:</b> Since version 0.9.7, PCRE filtering is built into 3proxy and does not require
a separate plugin. All pcre_* commands are available directly when 3proxy is compiled with
PCRE2 support (WITH_PCRE). The plugin line is no longer needed.</p>
<p>This filtering functionality can be used to create matching and replacement
rules with regular expressions for client requests, client and
server headers, and client and server data. It adds 3 additional
configuration commands:</p>
<pre>
pcre TYPE FILTER_ACTION REGEXP [ACE]
pcre_rewrite TYPE FILTER_ACTION REGEXP REWRITE_EXPRESSION [ACE]
pcre_extend FILTER_ACTION [ACE]
pcre_options OPTION1 [...]
</pre>
pcre - allows applying a rule for matching
<br>pcre_rewrite - in addition to 'pcre', allows substituting substrings
<br>pcre_extend - extends the ACL of the last pcre or pcre_rewrite command by
adding an additional ACE (like with allow/deny configuration commands).
<br>pcre_options - allows setting matching options. Available options are:
PCRE_CASELESS,
PCRE_MULTILINE,
PCRE_DOTALL,
PCRE_EXTENDED,
PCRE_ANCHORED,
PCRE_DOLLAR_ENDONLY,
PCRE_EXTRA,
PCRE_NOTBOL,
PCRE_NOTEOL,
PCRE_UNGREEDY,
PCRE_NOTEMPTY,
PCRE_UTF8,
PCRE_NO_AUTO_CAPTURE,
PCRE_NO_UTF8_CHECK,
PCRE_AUTO_CALLOUT,
PCRE_PARTIAL,
PCRE_DFA_SHORTEST,
PCRE_DFA_RESTART,
PCRE_FIRSTLINE,
PCRE_DUPNAMES,
PCRE_NEWLINE_CR,
PCRE_NEWLINE_LF,
PCRE_NEWLINE_CRLF,
PCRE_NEWLINE_ANY,
PCRE_NEWLINE_ANYCRLF,
PCRE_BSR_ANYCRLF,
PCRE_BSR_UNICODE
<ul>
<li>TYPE - type of filtered data. May contain one or more
(comma-delimited list) values:
<ul>
<li>request - content of the client's request, e.g., the HTTP GET request string.
(known problem: changing the request string doesn't change the IP of the host to connect to)
<li>cliheader - content of the client request headers, e.g., HTTP request headers.
<li>srvheader - content of the server's reply headers, e.g., HTTP status and headers.
<li>clidata - data received from the client, e.g., HTTP POST request data
<li>srvdata - data received from the server, e.g., an HTML page
</ul>
<li>FILTER_ACTION - action on match
<ul><li>allow - allow this request without checking the rest of the rules for the given type
<li>deny - deny this request without checking the rest of the rules
<li>dunno - continue with the rest of the rules (useful with pcre_rewrite)
</ul>
<li>REGEXP - PCRE (Perl) regular expression. Use * if no regexp matching
is required.
<li>REWRITE_EXPRESSION - substitution string. May contain Perl-style
substrings
(not tested) $1, $2. $0 means the whole matched string. \r and \n may be used
to insert new strings; the string may be empty ("").
<li>ACE - access control entry (user names, source IPs, destination IPs,
ports, etc.), absolutely identical to allow/deny/bandlimin commands.
The regular expression is only matched if the ACL matches the connection data.
Warning:
Regular expressions don't require authentication and cannot replace
authentication and/or allow/deny ACLs.
</ul>
<h4>Example:</h4>
<pre>
pcre request deny "porn|sex" user1,user2,user3 192.168.0.0/16
pcre srvheader deny "Content-type: application"
pcre_rewrite clidata,srvdata dunno "porn|sex|pussy" "***" baduser
pcre_extend deny * 192.168.0.1/16

<h3>Фильтрация PCRE (Perl Compatible Regular Expressions) в 3proxy</h3>
<p><b>Примечание:</b> Начиная с версии 0.9.7 фильтрация PCRE встроена в 3proxy и не требует
отдельного плагина. Все команды pcre_* доступны напрямую при компиляции 3proxy с поддержкой
PCRE2 (WITH_PCRE). Строка plugin больше не нужна.</p>
<p>Фильтрующий плагин используется для создания правил поиска и замены
регулярных выражений в запросе, заголовков запроса и ответа и данных.
Добавляет поддержку 3х новых команд в файле конфигурации:</p>
<pre>
pcre TYPE FILTER_ACTION REGEXP [ACE]
pcre_rewrite TYPE FILTER_ACTION REGEXP REWRITE_EXPRESSION [ACE]
pcre_extend FILTER_ACTION [ACE]
pcre_options OPTION1 [...]
</pre>
pcre - позволяет искать совпадения
<br>pcre_rewrite - дополнительно позволяет производить замену подстрок
<br>pcre_extend - расширяет ACL последней команды pcre или pcre_rewrite путем
добавления еще одной ACE (аналогично списку правил allow/deny).
<br>pcre_options - позволяет устанавливать опции поиска, доступны следующие опции:
PCRE_CASELESS,
PCRE_MULTILINE,
PCRE_DOTALL,
PCRE_EXTENDED,
PCRE_ANCHORED,
PCRE_DOLLAR_ENDONLY,
PCRE_EXTRA,
PCRE_NOTBOL,
PCRE_NOTEOL,
PCRE_UNGREEDY,
PCRE_NOTEMPTY,
PCRE_UTF8,
PCRE_NO_AUTO_CAPTURE,
PCRE_NO_UTF8_CHECK,
PCRE_AUTO_CALLOUT,
PCRE_PARTIAL,
PCRE_DFA_SHORTEST,
PCRE_DFA_RESTART,
PCRE_FIRSTLINE,
PCRE_DUPNAMES,
PCRE_NEWLINE_CR,
PCRE_NEWLINE_LF,
PCRE_NEWLINE_CRLF,
PCRE_NEWLINE_ANY,
PCRE_NEWLINE_ANYCRLF,
PCRE_BSR_ANYCRLF,
PCRE_BSR_UNICODE
<ul>
<li>TYPE - тип фильтруемых данных. Может содержать одно или
несколько (список через запятую) значений:
<ul>
<li>request - содержимое запроса клиента (например строка HTTP GET-запроса).
(в настоящий момент изменение запроса не приводит к изменению адреса запрашиваемого хоста)
<li>cliheader - содержимое заголовков запроса клиента, например заголовки HTTP
<li>srvheader - содержимое заголовков ответа сервера, например заголовки HTTP
<li>clidata - данные полученные от клиента, например данные POST-запроса
<li>srvdata - данные полученные от сервера, например содержимое HTML-страницы
</ul>
<li>FILTER_ACTION - действие при совпадении. Может принимать значение
<ul><li>allow - разрешить данный запрос без просмотра дальнейших правил
<li>deny - запретить данный запрос без просмотра дальнейших правил
<li>dunno - продолжить анализ правил (полезно для pcre_rewrite)
</ul>
<li>REGEXP - регулярное выражение в формате PCRE (perl). Используйте * если не
требуется проерка регулярного выражения.

<h3>3proxy SSL/TLS Support</h3>
<p><b>Note:</b> Since version 0.9.7, SSL/TLS support is built into 3proxy and does not require
a separate plugin. All ssl_* commands are available directly when 3proxy is compiled with
OpenSSL support (WITH_SSL). The plugin line is no longer needed.</p>
<p>SSL/TLS support can be used to transparently decrypt SSL/TLS data, provide TLS encryption
for proxy traffic, and authenticate using client certificates.</p>
<h4>For transparent certificate spoofing (MITM):</h4>
<br>ssl_mitm - spoof certificates for services started below. Usage without ssl_client_verify is insecure.
<br>ssl_nomitm - do not spoof certificates for services started below
<h4>To protect traffic to the server (https:// proxy):</h4>
ssl_serv (or ssl_server) - require TLS connection from clients for services below
<br>ssl_noserv (or ssl_noserver) - do not require TLS connection from clients for services below
<h4>To use TLS for upstream connections:</h4>
ssl_cli (or ssl_client) - establish TLS connection to upstream server for services below
<br>ssl_nocli (or ssl_noclient) - do not establish TLS connection to upstream server for services below
<h4>Parameters:</h4>

The cache may contain 3 files: 3proxy.pem - public
self-signed certificates (used if ssl_server_ca_file is not configured),
3proxy.key - key for public certificates, used if ssl_server_ca_key is not configured, server.key - this key is used if ssl_server_key is not configured to generate
spoofed certificates. If server.key is absent, 3proxy.key is used to generate certificates.
Generated certificates are placed in the same path.
<h4>MITM example:</h4>
<pre>
ssl_server_ca_file /path/to/cafile
ssl_server_ca_key /path/to/cakey
ssl_mitm
proxy -p3128
ssl_nomitm
proxy -p3129
</pre>
MITM's traffic with a spoofed certificate for the port 3128 proxy.
<h4>https:// proxy example:</h4>
<pre>
ssl_server_cert path_to_cert
ssl_server_key path_to_key
ssl_serv
proxy -p33128
ssl_noserv
proxy -p3128
</pre>
Creates an https:// proxy on port 33128 and an http:// proxy on port 3128
<h4>TLS client example (connect to upstream via TLS):</h4>
<pre>
ssl_client_cert /path/to/client.crt
ssl_client_key /path/to/client.key
ssl_client_verify
ssl_client_ca_file /path/to/ca.crt
ssl_cli
proxy -p3128
</pre>
Creates an HTTP proxy that connects to upstream servers via TLS with client certificate authentication.
<h4>Conditional TLS for parent proxy (ssl_client_mode 3):</h4>
<pre>
ssl_server_cert /path/to/server.crt
ssl_server_key /path/to/key
ssl_client_mode 3
auth strong
allow user1
parent 1000 https parent1.example.com 443
allow user2
parent 1000 socks5 parent2.example.com 1080
ssl_serv
ssl_cli
proxy -p3128
ssl_noserv
ssl_nocli
</pre>
Creates an HTTP proxy on port 3128 that uses TLS for client connections (ssl_serv). With ssl_client_mode 3, TLS handshake to parent proxy is performed only if the parent type ends with 's' (secure types). In this example, user1's traffic goes through an https parent proxy with TLS encryption, while user2's traffic goes through a regular socks5 parent without TLS. Secure parent types include: tcps, https, connects, connect+s, socks4s, socks5s, socks4+s, socks5+s, pop3s, smtps, ftps.
<h4>mTLS example (require client certificate):</h4>
<pre>
ssl_server_cert /path/to/server.crt
ssl_server_key /path/to/server.key
ssl_server_ca_file /path/to/ca.crt
ssl_server_verify
ssl_serv
proxy -p3128
</pre>
Creates an https:// proxy that requires client certificate authentication.

<h3>3proxy SSL/TLS поддержка</h3>
<p><b>Примечание:</b> Начиная с версии 0.9.7 поддержка SSL/TLS встроена в 3proxy и не требует
отдельного плагина. Все команды ssl_* доступны напрямую при компиляции 3proxy с поддержкой
OpenSSL (WITH_SSL). Строка plugin больше не нужна.</p>

<br><b>ssl_certcache</b> /path/to/cache/ - расположение кеша сгенерированных MITM-сертификатов. Кеш может содержать
файлы 3proxy.pem, 3proxy.key, server.key, которые используются как ssl_server_ca_file,
ssl_server_ca_key и ssl_server_key соответственно, если они не заданы. Если server.key не задан,
3proxy.key используется для генерации серверного сертификата.
<h4>Пример MITM:</h4>
<pre>
ssl_server_ca_file /path/to/cafile
ssl_server_ca_key /path/to/cakey
ssl_mitm
proxy -p3128
ssl_nomitm
proxy -p3129
</pre>
Перехватывается трафик в прокси на порту 3128.
<h4>Пример конфигурации https:// прокси:</h4>
<pre>
ssl_server_cert path_to_cert
ssl_server_key path_to_key
ssl_serv
proxy -p33128
ssl_noserv
proxy -p3128
</pre>
На порту 33128 создается https:// прокси, на порту 3128 - http:// прокси.
<h4>Пример TLS-клиента (соединение к вышестоящему серверу через TLS):</h4>
<pre>
ssl_client_cert /path/to/client.crt
ssl_client_key /path/to/client.key
ssl_client_verify
ssl_client_ca_file /path/to/ca.crt
ssl_cli

<h4>Условное TLS для parent прокси (ssl_client_mode 3):</h4>
<pre>
ssl_server_cert /path/to/server.crt
ssl_server_key /path/to/key
ssl_client_mode 3
auth strong
allow user1
parent 1000 https parent1.example.com 443
allow user2
parent 1000 socks5 parent2.example.com 1080
ssl_serv
ssl_cli
proxy -p3128
ssl_noserv
ssl_nocli
</pre>
Создается HTTP-прокси на порту 3128, использующий TLS для клиентских соединений (ssl_serv). При ssl_client_mode 3 TLS-рукопожатие с родительским прокси выполняется только если тип parent прокси заканчивается на 's' (защищённые типы). В данном примере трафик user1 идёт через https родительский прокси с TLS-шифрованием, а трафик user2 — через обычный socks5 родитель без TLS. Защищённые типы parent прокси: tcps, https, connects, connect+s, socks4s, socks5s, socks4+s, socks5+s, pop3s, smtps, ftps.
<h4>Пример mTLS (требование клиентского сертификата):</h4>
