  • responses to requests with status code 304 (not modified)

cookies (list<CookieUDR>)

This field contains any Cookie UDRs included.

headers (map<string,list<string>>)

This field is populated by all the headers present in the response. The map keys contain header field names and the content is stored in the corresponding map values.

httpVersion (string)

This field contains the HTTP version; HTTP/1 or HTTP/2.

mimetype (string)

The type of the content, for example "text/html", "image/gif", etc.

openAPIUDR (DRUDR)

This field is used if an OpenAPI profile has been associated with the HTTP/2 Server agent.

statusCode (int)

The HTTP status code, for example: 200 - OK, 404 - Not Found, etc.

MultipartSegment

The MultipartSegment UDR is used when sending requests containing multiple types of content, or when the content has been split up in multiple parts.
 The following fields are included in the MultipartSegment UDR:

Field

Description

Field

Description

content (bytearray)

Field

Description

claims (map<sting,any>)

The payload and any additional claims, that is, any additional user information required for authentication, for example website or zoneinfo.

token (string)

The security token used for authentication.

username (string)

The user name.

RequestCycle

When the HTTP/2 Server agent receives a request, it converts it to a RequestCycle UDR that is routed into the workflow. The UDR will then get the Response field populated in the workflow before being routed back to the HTTP/2 Server agent.

The following fields are included in the RequestCycle UDR:

Field

Description

Field

Description

authToken (HttpAuthTokenUDR)

If Token Authentication is selected in the agent configuration, the AuthToken UDR contains the required information for authentication.

body (bytearray)

This field contains the message body, that is the payload, of the request. For a request, the presence of a message body is indicated by the presence of a Content-Length or Transfer-Encoding field.

This field can be used in the workflow configuration to keep track of, and use, internal workflow information related to a RequestCycle UDR.

For instance, before you route a RequestCycle UDR to the HTTP/2 agent, store the TCPIPUDR from a TCP/IP collection agent in the Context field. You can then read the TCPIPUDR from the Context field in the RequestCycle UDR that contains the answer, and use it to send back a response to the TCP/IP collection agent.

The field will only be set when Route Error to APL is enabled on the HTTP/2 Server agent.

followRedirects (boolean)

This controls whether the HTTP/2 Client agent should automatically follow redirects.

The default value is true.
