If the method succeeds, rc is 0 else rc > 0. Values above 0x8000 indicate Warnings.

If the method succeeds, message is NULL else message contains Error/Warning message.

List of nshttpprofiles

Name of the HTTP profile to be displayed.

Dropping of invalid HTTP requests/responses

Invalidating HTTP 0.9 requests

Invalidating CONNECT HTTP requests

Invalidating TRACE HTTP requests

Invalidating RFC7230 Non-Compliant

Mark Http header with extra white space as invalid

Compression on PUSH packet

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

Maximum connections in reusepool

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

Number of entities using this profile

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

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.

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.

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

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.

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

Disabling weblog option

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

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

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

Choose whether to enable support for HTTP/2.

Choose whether to enable support for Direct HTTP/2.

Choose whether to enable strict HTTP/2 cipher selection

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.

Choose whether to enable support for Alternative Services.

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

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.

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

Maximum number of concurrent streams that is allowed per connection.

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

Initial window size for stream level flow control, in bytes.

Maximum size of the header compression table used to decode header blocks, in bytes.

Minimum number of HTTP2 connections established to backend server, on receiving HTTP requests from client before multiplexing the streams into the available HTTP/2 connections.

Maximum number of PING frames allowed in HTTP2 connection per minute

Maximum number of SETTINGS frames allowed in HTTP2 connection per minute

Maximum number of outgoing RST_STREAM frames allowed in HTTP/2 connection per minute

Maximum number of empty frames allowed in HTTP2 connection per minute

Maximum number of incoming RST_STREAM frames allowed in HTTP/2 connection per minute

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

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

Set to DISABLED for gRPC without a length delimitation.

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.

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.

Number of bytes allowed for header field for HTTP header. If number of bytes exceeds beyond configured value, then request will be marked invalid

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.

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.

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

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 4*T is considered tolerable. Any transaction responding in more than 4*T 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.

Choose whether to enable support for HTTP/3.

Maximum size of the HTTP/3 header field section, in bytes.

Maximum size of the HTTP/3 QPACK dynamic header table, in bytes.

Maximum number of HTTP/3 streams that can be blocked while HTTP/3 headers are being decoded.

Choose whether to enable support for WebTransport over HTTP/3.

Application pipeline request buffering size, in bytes.

Allow only word character hyphen [A-Za-z0-9_]

Host header validation

Maximum number of allowed occurrences of header fields that share the same field name. This threshold is enforced only for well-known header field names recognized by NetScaler, and also for custom header field names present in configured expressions. The default value of 0 indicates that there is no threshold.

Minimum HTTP/3 server connections in active pool

Display warning if Drop invalid reqs is disabled in the profile

Pass protocol upgrade request to the server.

Choose whether to enable HTTP/2 Extended CONNECT mechanism.
