<condition> element

An element that lets you choose conditions for the rule. Note, all conditions must be met for the rule to be run (unless "next" is set to "or" obvoiusly).

Value can be any Regular Expression (Perl5 style).

Attribute	Possible Value	Explanation
type (optional)	header (default)	If used, the header name must be specified in the "name" attribute.
	method	The method of the request. GET, POST, HEAD etc.
	port	The port that the web application server is running on.
	time	Current time at the server (this will be the number of seconds since 00:00:00 1970-01-01 UTC otherwise known as unix time). i.e. (new Date()).getTime() This can be used for making sure content goes live only at a time you set.
	year	Current year at the server. i.e. (Calendar.getInstance()).get(Calendar.YEAR)
	month	Month at the server. January is 0 i.e. (Calendar.getInstance()).get(Calendar.MONTH)
	dayofmonth	Day of the month at the server. March first is 1 i.e. (Calendar.getInstance()).get(Calendar.DAY_OF_MONTH)
	dayofweek	Day of the week at the server. Saturday is 1, Sunday is 7 i.e. (Calendar.getInstance()).get(Calendar.DAY_OF_WEEK)
	ampm	AM or PM time at the server. i.e. (Calendar.getInstance()).get(Calendar.AM_PM)
	hourofday	The hour of the day (24 hour clock) at the server. 10pm is 22 i.e. (Calendar.getInstance()).get(Calendar.HOUR_OF_DAY)
	minute	The minute field of the current time at the server. i.e. (Calendar.getInstance()).get(Calendar.MINUTE)
	second	The second field of the current time at the server. i.e. (Calendar.getInstance()).get(Calendar.SECOND)
	millisecond	The millisecond field of the current time at the server. i.e. (Calendar.getInstance()).get(Calendar.MILLISECOND)
	attribute	Will check the value of a request attribute (don't confuse this with parameter!), name must be set when using this type. i.e. request.getAttribute([name])
	auth-type	Will check the value of a request attribute (don't confuse this with parameter!) i.e. request.getAuthType()
	character-encoding	The character encoding of the imcoming request. i.e. request.getCharacterEncoding()
	content-length	The length of the imcoming request (can be useful if you want to deny large requests). i.e. request.getContentLength()
	content-type	The type of the imcoming request. (this is probably not that useful) i.e. request.getContentType()
	context-path	The context path of the imcoming request. i.e. request.getContextPath()
	cookie	The value of a cookie, note, name must be specified to use this i.e. request.getCookies() the find we the one with [name] specified and check the value.
	parameter	A tidier way of checking request parameters than looking for them in the query string. This will check for the parameter in GET or POST, note, name must be specified. i.e. request.getParameter([name])
	path-info	i.e. request.getPathInfo()
	path-translated	i.e. request.getPathTranslated()
	protocol	The protocol used to make the request, e.g. HTTP/1.1 i.e. request.getProtocol()
	query-string	The query string used to make the request (if any), e.g. id=2345&name=bob i.e. request.getQueryString()
	remote-addr	The IP address of the host making the request, e.g. 123.123.123.12 i.e. request.getRemoteAddr()
	remote-host	The host name of the host making the request, e.g. 123qw-dsl.att.com (note, this will only work if your app server is configured to lookup host names, most aren't). i.e. request.getRemoteHost()
	remote-user	The login of the user making this request, if the user has been authenticated, e.g. bobt i.e. request.getRemoteUser()
	requested-session-id	Returns the session ID specified by the client, e.g. 2344asd234sada4 i.e. request.getRequestedSessionId()
	request-uri	Returns the part of this request's URL from the protocol name up to the query string in the first line of the HTTP request i.e. request.getRequestURI()
	request-url	Reconstructs the URL the client used to make the request. The returned URL contains a protocol, server name, port number, and server path, but it does not include query string parameters. i.e. request.getRequestURL()
	session-attribute	(note, name must be set) i.e. session.getAttribute([name])
	session-isnew	Weather the session is new or not. i.e. session.isNew()
	server-name	The host name of the server to which the request was sent (from the host header not the machine name). i.e. request.getServerName()
	scheme	The scheme used for the request, e.g. http or https i.e. request.getScheme()
	user-in-role	(Note, the value for this cannot be a regular expression) i.e. request.isUserInRole([value])
name (optional)	(can be anything)	If type is header, this specifies the name of the HTTP header used to run the value against.
next (optional)	and (default)	The next "rule" and this "rule" must match.
	or	The next "rule" or this "condition" may match.
operator (optional)	equal (default)	Equals. The operator to be used when the condition is run.
	notequal	Not equal to. (i.e. request value != condition value). Note, this operator only work with numeric rule types.
	greater	Greater than. (i.e. request value > condition value). Note, this operator only work with numeric rule types.
	less	Less than. (i.e. request value < condition value). Note, this operator only work with numeric rule types.
	greaterorequal	Greater to or equal to. (i.e. request value >= condition value). Note, this operator only work with numeric rule types.
	lessorequal	Less than or equal to. (i.e. request value <= condition value). Note, this operator only work with numeric rule types.

Examples:

    <condition name="user-agent" operator="notequal">Mozilla/[1-4]</condition>

    <condition type="user-in-role" operator="notequal">bigboss</condition>

    <condition name="host" operator="notequal">www.example.com</condition>

    <condition type="method" next="or">PROPFIND</condition>
    <condition type="method">PUT</condition>
