설정 지시자

 

RewriteCond TestString CondPattern [flags]

RewriteCond는 룰의 상태를 정의하며 RewriteRule 지시자전에 하나이상의 RewriteCond가 올수 있습니다.

먼저 나온룰이 매치될 경우 다음룰이 작용됩니다.

 

1. TestString

다음과 같은 내용이 올수 있습니다.

 

1) RewriteRule backreferences(RewriteRule 후방참조) -> form $N (0 <= N <= 9)

RewriteEngine on

RewriteCond   /mirror/of/remotesite/$1           -U

RewriteRule   ^http://www\.remotesite\.com/(.*)$ /mirror/of/remotesite/$1

위 예에서 $1은 아래 RewriteRule의 (.*)를 참조합니다.

 

2) RewriteCond backreferences(RewriteRule 후방참조) -> form %N (1 <= N <= 9)

##

##  vhost.map

##

www.vhost1.dom:80  /path/to/docroot/vhost1

www.vhost2.dom:80  /path/to/docroot/vhost2

     :

www.vhostN.dom:80  /path/to/docroot/vhostN

##

##  httpd.conf

##

    :

#   use the canonical hostname on redirects, etc.

UseCanonicalName on

    :

#   add the virtual host in front of the CLF-format

CustomLog  /path/to/access_log  "%{VHOST}e %h %l %u %t \"%r\" %>s %b"

    :

#   enable the rewriting engine in the main server

RewriteEngine on

#   define two maps: one for fixing the URL and one which defines

#   the available virtual hosts with their corresponding

#   DocumentRoot.

RewriteMap    lowercase    int:tolower

RewriteMap    vhost        txt:/path/to/vhost.map

 

#   Now do the actual virtual host mapping

#   via a huge and complicated single rule:

#

#   1. make sure we don't map for common locations

RewriteCond   %{REQUEST_URI}  !^/commonurl1/.*

RewriteCond   %{REQUEST_URI}  !^/commonurl2/.*

    :

RewriteCond   %{REQUEST_URI}  !^/commonurlN/.*

#

#   2. make sure we have a Host header, because

#      currently our approach only supports

#      virtual hosting through this header

RewriteCond   %{HTTP_HOST}  !^$

#

#   3. lowercase the hostname

RewriteCond   ${lowercase:%{HTTP_HOST}|NONE}  ^(.+)$

#

#   4. lookup this hostname in vhost.map and

#      remember it only when it is a path

#      (and not "NONE" from above)

RewriteCond   ${vhost:%1}  ^(/.*)$

#

#   5. finally we can map the URL to its docroot location

#      and remember the virtual host for logging purposes

RewriteRule   ^/(.*)$   %1/$1  [E=VHOST:${lowercase:%{HTTP_HOST}}]

    :

위 예제는 RewriteCond   ${vhost:%1}  ^(/.*)$ 에서 %1은 바로위 RewriteCond의 (.+)를 참조합니다.

 

3) RewriteMap expansions(RewriteMap 확장)   -> form ${mapname:key|default}

위 예제에서 RewriteCond   ${vhost:%1}  ^(/.*)$

 

4) Server-Variables(시스템 변수)    -> form %{ NAME_OF_VARIABLE }

HTTP headers:

HTTP_USER_AGENT
HTTP_REFERER
HTTP_COOKIE
HTTP_FORWARDED
HTTP_HOST
HTTP_PROXY_CONNECTION
HTTP_ACCEPT

connection & request:

REMOTE_ADDR
REMOTE_HOST
REMOTE_PORT
REMOTE_USER
REMOTE_IDENT
REQUEST_METHOD
SCRIPT_FILENAME
PATH_INFO
QUERY_STRING
AUTH_TYPE

server internals:

DOCUMENT_ROOT
SERVER_ADMIN
SERVER_NAME
SERVER_ADDR
SERVER_PORT
SERVER_PROTOCOL
SERVER_SOFTWARE

date and time:

TIME_YEAR
TIME_MON
TIME_DAY
TIME_HOUR
TIME_MIN
TIME_SEC
TIME_WDAY
TIME

specials:

API_VERSION
THE_REQUEST
REQUEST_URI
REQUEST_FILENAME
IS_SUBREQ
HTTPS

위 예제에서 RewriteCond   %{HTTP_HOST}  !^$

 

2. CondPattern

펄 호환 정규표현식입니다. 정규표현식외 아래 것들이 올수 있습니다.

-'<CondPattern' (lexicographically precedes)

-'>CondPattern' (lexicographically follows)

-'=CondPattern' (lexicographically equal)

-'-d' (is directory)

-'-f' (is regular file)

-'-s' (is regular file, with size)

-'-l' (is symbolic link)

-'-x' (has executable permissions)

-'-F' (is existing file, via subrequest)

-'-U' (is existing URL, via subrequest)

아래 예는 보시면 %{REQUEST_FILENAME}이 크기가 있는 정규파일이 아니라면의 의미가 됩니다.

RewriteCond %{REQUEST_FILENAME}   !-s

RewriteRule ^page\.html$          page.cgi   [T=application/x-httpd-cgi,L]

 

3. flags

CondPattern뒤 세번째 아규먼트로 [flags]가 올수 있습니다.

- 'nocase|NC'(no case)

- 'ornext|OR'(or next condition)

- 'novary|NV'(no vary) -> HTTP header가 상태에 사용될 경우, 응답 vary 헤더에 해당 헤러가 들어가지 않도록 합니다.

아래 예에서 사용법을 보실수 있습니다.

RewriteEngine on

RewriteMap    hosts-deny  txt:/path/to/hosts.deny

RewriteCond   ${hosts-deny:%{REMOTE_HOST}|NOT-FOUND} !=NOT-FOUND [OR]

RewriteCond   ${hosts-deny:%{REMOTE_ADDR}|NOT-FOUND} !=NOT-FOUND

RewriteRule   ^/.*  -  [F]
