HTTP profile (object)

HTTP profile with configurable options

Properties (* = required):

name	type(s)	default	allowed values	description
/*/
allowBlankSpaceAfterHeaderName	boolean	false	true, false	Specifies whether to allow blank space in an HTTP header between the header name and the separator colon in an HTTP request or response. Requires TMOS version 16.1 or newer.
allowedResponseHeaders	array			By default BIG-IP AS3 passes HTTP headers in responses from pool members to clients unaltered. You may list names of allowed response headers here and BIG-IP AS3 removes any you do not list from responses.
class*	string		“HTTP_Profile”
cookiePassphrase	object			Used to create secret key for cookie encryption (when missing, BIG-IP AS3 uses a system-generated key),A passphrase (passphrase property),A value: (a) in a cryptogram in this object; (b) in a cryptogram elsewhere in this declaration; or (c) available from a URL
encryptCookies	array			List cookies to encrypt en-route to the client and decrypt en-route to a pool member
enforceRFCCompliance	boolean	false	true, false	BIG-IP LTM performs basic RFC compliance checks as described in the latest RFC for the HTTP protocol. If a client request fails these checks, then the connection is reset. Requires TMOS version 15.0 or newer.
fallbackRedirect	string			Domain name (or IP address) of service (if any) to which BIG-IP AS3 should redirect a request when no pool member is responsive or selected pool member returns a fallbackStatusCode
fallbackStatusCodes	array			When a pool member responds to a request with one of these HTTP status codes (for example, 500), redirect the client to the fallbackRedirect
hstsIncludeSubdomains	boolean	true	true, false	If true then HSTS headers (see hstsInsert) will tell clients to apply HSTS settings to the hostnames of this service and all their possible subdomains. Warning: an incorrect value here can make multiple websites unreachable, not just this service
hstsInsert	boolean	false	true, false	If true, insert HSTS (HTTP Strict Transport Security) headers into responses sent to clients (default false). Warning: misconfiguration of HSTS can make a website unreachable
hstsPeriod	integer	7862400	0 - 4294967295	If hstsInsert is true, this value tells each client how long (in seconds; default 7862400 equals 91 days) to wait before refreshing HSTS settings for this service. Warning: once a client receives erroneous HSTS settings it will ignore any attempt to correct them until this period has expired
hstsPreload	boolean	false	true, false	If true, include the domain for the web site associated with this HTTP profile in the browser’s preload list. This forces the client to send packets over SSL/TLS.
insertHeader	object			You may insert one header into each request before BIG-IP AS3 sends it to a pool member. The header value may be a simple string or the result of an iRules TCL expression (for example, [IP::client_addr]). This is the most efficient way to insert a single header; to insert multiple headers use an iRule or an Endpoint policy
knownMethods	array	“CONNECT”		List of HTTP request methods BIG-IP AS3 should recognize as normal. Any method not in this list will provoke the ‘unknownMethodAction’ action
label	string		“^[^x00-x1fx22#&*<>?x5b-x5d`x7f]*$”	Optional friendly name for this object. Allows 0-64 chars, excluding a few likely to cause trouble with string searching, JS, TCL, or HTML
maxRequests	integer	0	0 - 2147483647	When BIG-IP AS3 has processed more than this number of requests through a connection, the system closes it. Default 0 means permit unlimited requests
multiplexStatusReuse	string	“200 206”	“^([24]dds?)+$”	Specifies what status codes will reuse connections from Multiplex. Default value is 200 206.
multiplexTransformations	boolean	true	true, false	If true (default), BIG-IP AS3 adjusts request headers to work properly when the virtual server uses a Multiplex profile
otherXFF	array			Names of request headers to treat as equivalent to X-Forwarded-For (see trustXFF)
pipelineAction	string	“allow”	“allow”, “reject”, “pass-through”	Default ‘allow’ means clients may pipeline HTTP/1.1 requests to pool members which support pipelining. Otherwise, ‘reject’ prevents pipelining, and ‘pass-through’ causes the connection to switch to pass-through mode when the system detects pipelining
profileWebSocket	object			Deprecated. Specifies the WebSocket profile that will be used on Services alongside this HTTP profile. When the ‘profileWebSocket’ property is used on a Service, it will supersede this property.,Reference to a WebSocket Profile
proxyConnectEnabled	boolean	false	true, false	Determines if a proxy connection profile will be created
proxyType	string	“reverse”	“reverse”, “transparent”, “explicit”	Default value ‘reverse’ is usually appropriate. You may use ‘transparent’ when virtual server will handle a mix of HTTP and non-HTTP traffic. You may use ‘explicit’ when clients will ask ADC to proxy connections to arbitrary remote services
remark	string		“^[^x00-x1fx22x5cx7f]*$”	Arbitrary (brief) text pertaining to this object. Allows 0-64 chars, excluding only control characters, double-quote, and backslash. This is permissive enough that you should worry about XSS attacks
requestChunking	string	“preserve”	“selective”, “preserve”, “rechunk”, “sustain”	Controls handling of HTTP payload chunking in requests from clients (default is ‘preserve’). Note: ‘selective’ and ‘preserve’ will be translated to ‘sustain’ when TMOS version is 15.0 or newer and ‘sustain’ will be translated to ‘preserve’ on older TMOS versions.
responseChunking	string	“selective”	“selective”, “preserve”, “unchunk”, “rechunk”, “sustain”	Controls handling of HTTP payload chunking in responses from pool members (default ‘selective’ adapts to most situations). Note: ‘selective’ and ‘preserve’ will be translated to ‘sustain’ when TMOS version is 15.0 or newer and ‘sustain’ will be translated to ‘selective’ on older TMOS versions.
rewriteRedirects	string	“none”	“none”, “all”, “matching”, “addresses”	In selected Location-header values (default none) of redirect responses from pool members, change protocol HTTP to HTTPS before passing redirects to clients
serverHeaderValue	string	“BigIP”		Server header value to place in responses generated by the ADC itself (not obtained from a pool member)
trustXFF	boolean	false	true, false	If true, WAF (ASM) and AVR may trust X-Forwarded-For headers found in incoming requests and report statistics using client IP addresses appearing in them (default false). Use this feature only when you control upstream gateway(s)
unknownMethodAction	string	“allow”	“allow”, “reject”, “pass-through”	Default ‘allow’ means clients may make HTTP requests using unknown methods. Otherwise, ‘reject’ means to discard any unknown-method request and reject the client connection, and ‘pass-through’ causes the connection to switch to pass-through mode upon the first unknown-method request
viaHost	string			Hostname to place in Via header when viaRequest or viaResponse is ‘append’
viaRequest	string	“remove”	“append”, “preserve”, “remove”	Controls treatment of Via: headers in requests from clients. When set to ‘append’ BIG-IP AS3 requires viaHost
viaResponse	string	“remove”	“append”, “preserve”, “remove”	Controls treatment of Via: headers in responses from pool members. When set to ‘append’ BIG-IP AS3 requires viaHost
webSocketMasking	string	“unmask”	“preserve”, “remask”, “selective”, “unmask”	Deprecated. WebSocket stream data is always masked from client to ADC and from ADC to server. Default value ‘unmask’ makes stream data passing through visible to ADC security policy and/or iRules attached to the service. ‘selective’ unmasks stream data only when a security policy is attached. ‘preserve’ passes data through masked (unreadable by security policy). ‘remask’ causes different masking keys to be used on client and server sides. When specified the property ‘profileWebSocket’ supersedes this property.
webSocketsEnabled	boolean	false	true, false	Deprecated. When true, allow clients to initiate WebSocket connections (default false). When specified the property ‘profileWebSocket’ supersedes this property.
whiteOutHeader	string		“^[^x00-x20x22:x5cx7f-xff]+$”	You may name one request header you want whited-out of each request before BIG-IP AS3 sends it to a pool member. To remove more than a single named header, use an iRule or an Endpoint policy. (Whiting-out a header leaves its name but replaces its value in the request with space characters (ASCII 0x20) to avoid changing the length of the headers.)
xForwardedFor	boolean	true	true, false	If true, insert an X-Forwarded-For header carrying the client IP address into each HTTP request sent to a pool member (default true)
