- Field Detail
  - conditions
```
protected RewriteCond[] conditions
```
  - pattern
```
protected ThreadLocal<Pattern> pattern
```
  - substitution
```
protected Substitution substitution
```
  - patternString
```
protected String patternString
```
  - substitutionString
```
protected String substitutionString
```
  - chain
```
protected boolean chain
```
    This flag chains the current rule with the next rule (which itself can be chained with the following rule, etc.). This has the following effect: if a rule matches, then processing continues as usual, i.e., the flag has no effect. If the rule does not match, then all following chained rules are skipped. For instance, use it to remove the ``.www'' part inside a per-directory rule set when you let an external redirect happen (where the ``.www'' part should not to occur!).
  - cookie
```
protected boolean cookie
```
    This sets a cookie on the client's browser. The cookie's name is specified by NAME and the value is VAL. The domain field is the domain of the cookie, such as '.apache.org',the optional lifetime is the lifetime of the cookie in minutes, and the optional path is the path of the cookie
  - cookieName
```
protected String cookieName
```
  - cookieValue
```
protected String cookieValue
```
  - cookieDomain
```
protected String cookieDomain
```
  - cookieLifetime
```
protected int cookieLifetime
```
  - cookiePath
```
protected String cookiePath
```
  - cookieSecure
```
protected boolean cookieSecure
```
  - cookieHttpOnly
```
protected boolean cookieHttpOnly
```
  - cookieSubstitution
```
protected Substitution cookieSubstitution
```
  - cookieResult
```
protected ThreadLocal<String> cookieResult
```
  - env
```
protected boolean env
```
    This forces a request attribute named VAR to be set to the value VAL, where VAL can contain regexp back references $N and %N which will be expanded. Multiple env flags are allowed.
  - envName
```
protected ArrayList<String> envName
```
  - envValue
```
protected ArrayList<String> envValue
```
  - envSubstitution
```
protected ArrayList<Substitution> envSubstitution
```
  - envResult
```
protected ArrayList<ThreadLocal<String>> envResult
```
  - forbidden
```
protected boolean forbidden
```
    This forces the current URL to be forbidden, i.e., it immediately sends back a HTTP response of 403 (FORBIDDEN). Use this flag in conjunction with appropriate RewriteConds to conditionally block some URLs.
  - gone
```
protected boolean gone
```
    This forces the current URL to be gone, i.e., it immediately sends back a HTTP response of 410 (GONE). Use this flag to mark pages which no longer exist as gone.
  - host
```
protected boolean host
```
    Host. This means this rule and its associated conditions will apply to host, allowing host rewriting (ex: redirecting internally *.foo.com to bar.foo.com).
  - last
```
protected boolean last
```
    Stop the rewriting process here and don't apply any more rewriting rules. This corresponds to the Perl last command or the break command from the C language. Use this flag to prevent the currently rewritten URL from being rewritten further by following rules. For example, use it to rewrite the root-path URL ('/') to a real one, e.g., '/e/www/'.
  - next
```
protected boolean next
```
    Re-run the rewriting process (starting again with the first rewriting rule). Here the URL to match is again not the original URL but the URL from the last rewriting rule. This corresponds to the Perl next command or the continue command from the C language. Use this flag to restart the rewriting process, i.e., to immediately go to the top of the loop. But be careful not to create an infinite loop!
  - nocase
```
protected boolean nocase
```
    This makes the Pattern case-insensitive, i.e., there is no difference between 'A-Z' and 'a-z' when Pattern is matched against the current URL.
  - noescape
```
protected boolean noescape
```
    This flag keeps mod_rewrite from applying the usual URI escaping rules to the result of a rewrite. Ordinarily, special characters (such as '%', '$', ';', and so on) will be escaped into their hexcode equivalents ('%25', '%24', and '%3B', respectively); this flag prevents this from being done. This allows percent symbols to appear in the output, as in RewriteRule /foo/(.*) /bar?arg=P1\%3d$1 [R,NE] which would turn '/foo/zed' into a safe request for '/bar?arg=P1=zed'.
  - nosubreq
```
protected boolean nosubreq
```
    This flag forces the rewriting engine to skip a rewriting rule if the current request is an internal sub-request. For instance, sub-requests occur internally in Apache when mod_include tries to find out information about possible directory default files (index.xxx). On sub-requests it is not always useful and even sometimes causes a failure to if the complete set of rules are applied. Use this flag to exclude some rules. Use the following rule for your decision: whenever you prefix some URLs with CGI-scripts to force them to be processed by the CGI-script, the chance is high that you will run into problems (or even overhead) on sub-requests. In these cases, use this flag.
  - qsappend
```
protected boolean qsappend
```
    This flag forces the rewriting engine to append a query string part in the substitution string to the existing one instead of replacing it. Use this when you want to add more data to the query string via a rewrite rule.
  - redirect
```
protected boolean redirect
```
    Prefix Substitution with http://thishost[:thisport]/ (which makes the new URL a URI) to force a external redirection. If no code is given a HTTP response of 302 (MOVED TEMPORARILY) is used. If you want to use other response codes in the range 300-400 just specify them as a number or use one of the following symbolic names: temp (default), permanent, seeother. Use it for rules which should canonicalize the URL and give it back to the client, e.g., translate ``/~'' into ``/u/'' or always append a slash to /u/user, etc. Note: When you use this flag, make sure that the substitution field is a valid URL! If not, you are redirecting to an invalid location! And remember that this flag itself only prefixes the URL with http://thishost[:thisport]/, rewriting continues. Usually you also want to stop and do the redirection immediately. To stop the rewriting you also have to provide the 'L' flag.
  - redirectCode
```
protected int redirectCode
```
  - skip
```
protected int skip
```
    This flag forces the rewriting engine to skip the next num rules in sequence when the current rule matches. Use this to make pseudo if-then-else constructs: The last rule of the then-clause becomes skip=N where N is the number of rules in the else-clause. (This is not the same as the 'chain|C' flag!)
  - type
```
protected boolean type
```
    Force the MIME-type of the target file to be MIME-type. For instance, this can be used to setup the content-type based on some conditions. For example, the following snippet allows .php files to be displayed by mod_php if they are called with the .phps extension: RewriteRule ^(.+\.php)s$ $1 [T=application/x-httpd-php-source]
