show ns httpProfile

Displays information about HTTP profiles configured on the appliance.

Synopsis

show ns httpProfile []

Arguments

name Name of the HTTP profile to be displayed. If a name is not provided, information about all HTTP profiles is shown.

Output

dropInvalReqs Dropping of invalid HTTP requests/responses

markHttp09Inval Invalidating HTTP 0.9 requests

markConnReqInval Invalidating CONNECT HTTP requests

markTraceReqInval Invalidating TRACE HTTP requests

markRfc7230NonCompliantInval Invalidating RFC7230 Non-Compliant

markHTTPHeaderExtraWSError Mark Http header with extra white space as invalid

cmpOnPush Compression on PUSH packet

conMultiplex Reuse server connections for requests from more than one client connections.

maxReusePool Maximum connections in reusepool

webSocket HTTP connection to be upgraded to a web socket connection. Once upgraded, Citrix ADC does not process Layer 7 traffic on this connection.

refCnt Number of entities using this profile

stateflag State flag

dropExtraCRLF Drop any extra 'CR' and 'LF' characters present after the header.

incompHdrDelay Maximum time to wait, in milliseconds, between incomplete header packets. If the header packets take longer to arrive at Citrix ADC, the connection is silently dropped.

reqTimeout Time, in seconds, within which the HTTP request must complete. If the request does not complete within this time, the specified request timeout action is executed. Zero disables the timeout.

adptTimeout Adapts the configured request timeout based on flow conditions. The timeout is increased or decreased internally and applied on the flow.

reqTimeoutAction Action to take when the HTTP request does not complete within the specified request timeout duration. You can configure the following actions: * RESET - Send RST (reset) to client when timeout occurs. * DROP - Drop silently when timeout occurs. * Custom responder action - Name of the responder action to trigger when timeout occurs, used to send custom message.

dropExtraData Drop any extra data when server sends more data than the specified content-length.

webLog Disabling weblog option

clientIpHdrExpr Name of the header that contains the real client IP address.

maxReq Maximum number of requests allowed on a single connection. Zero implies no limit on the number of requests.

persistentETag Generate the persistent Citrix ADC specific ETag for the HTTP response with ETag header.

http2 Choose whether to enable support for HTTP/2.

http2Direct Choose whether to enable support for Direct HTTP/2.

http2StrictCipher Choose whether to enable strict HTTP/2 cipher selection

http2AltSvcFrame Choose whether to enable support for sending HTTP/2 ALTSVC frames. When enabled, the ADC sends HTTP/2 ALTSVC frames to HTTP/2 clients, instead of the Alt-Svc response header field. Not applicable to servers.

altsvc Choose whether to enable support for Alternative Services.

altSvcValue Configure a custom Alternative Services header value that should be inserted in the response to advertise a HTTP/SSL/HTTP_QUIC vserver.

http2MaxHeaderListSize Maximum size of header list that the Citrix ADC is prepared to accept, in bytes. NOTE: The actual plain text header size that the Citrix ADC accepts is limited by maxHeaderLen. Please change maxHeaderLen parameter as well when modifying http2MaxHeaderListSize.

http2MaxFrameSize Maximum size of the frame payload that the Citrix ADC is willing to receive, in bytes.

http2MaxConcurrentStreams Maximum number of concurrent streams that is allowed per connection.

http2InitialConnWindowSize Initial window size for connection level flow control, in bytes.

grpcHoldLimit Maximum size in bytes allowed to buffer gRPC packets till trailer is received

grpcHoldTimeout Maximum time in milliseconds allowed to buffer gRPC packets till trailer is received. The value should be in multiples of 100

grpcLengthDelimitation Set to DISABLED for gRPC without a length delimitation.

reusePoolTimeout Idle timeout (in seconds) for server connections in re-use pool. Connections in the re-use pool are flushed, if they remain idle for the configured timeout.

maxHeaderLen Number of bytes to be queued to look for complete header before returning error. If complete header is not obtained after queuing these many bytes, request will be marked as invalid and no L7 processing will be done for that TCP connection.

rtspTunnel Allow RTSP tunnel in HTTP. Once application/x-rtsp-tunnelled is seen in Accept or Content-Type header, Citrix ADC does not process Layer 7 traffic on this connection.

minReUsePool Minimum limit on the number of connections, from the Citrix ADC to a particular server that are kept in the reuse pool. This setting is helpful for optimal memory utilization and for reducing the idle connections to the server just after the peak time. Zero implies no limit on reuse pool size.

builtin Flag to determine if http profile is built-in or not

feature The feature to be checked while applying this config

apdexSvrRespTimeThreshold This option sets the satisfactory threshold (T) for server response time in milliseconds to be used for APDEX calculations. This means a transaction responding in less than this threshold is considered satisfactory. Transaction responding between T and 4T is considered tolerable. Any transaction responding in more than 4T time is considered frustrating. Citrix ADC maintains stats for such tolerable and frustrating transcations. Server Response time related apdex counters are only updated on backend services or a backend vserver which is not accepting client traffic.

apdexCltRespTimeThreshold This option sets the satisfactory threshold (T) for client response time in milliseconds to be used for APDEX calculations. This means a transaction responding in less than this threshold is considered satisfactory. Transaction responding between T and 4T is considered tolerable. Any transaction responding in more than 4T time is considered frustrating. Citrix ADC maintains stats for such tolerable and frustrating transcations. And client response time related apdex counters are only updated on a vserver which receives clients traffic.
