URL Adapter Reference


This page explains the URL Adapter in Bridge context. If you were looking for the same information regarding the PAS Designer, refer to URL Adapter in the Designer guide.

All URL adapter parameters, that are specified on the <<URLAlias>> in the component diagram, can also be supplied dynamically via action script. Find below a list of all relevant parameters of the URL adapter and their description.

With the URL adapter, it is possible to get and put messages via file transfer protocols: FTP, FTPS and SFTP. These protocols often get confused and mixed up due to the similarity in function and names. Please refer to Using the URL Adapter with the FTP Protocol and Related Protocols for a distinction and more information on the usage with the URL adapter.

Request Http Header Roles
(requestHttpHeaderRoles)

Builder 7.12.0 Runtime 2020.12 In the context of HTTP based adapters (URL, REST, SOAP), enable automatic header generation for the listed headers. These definitions overwrite the default behavior, and X-Transaction-Id, X-Request-Id, X-Sender-Host and/or X-Sender-Service will be substituted by this definition.

requestHttpHeaderRoles can hold a list of definitions in format <http header name>:<role>, that will automatically be generated for each adapter call on this alias. <role> can be one of the listed allowed values (one list entry per line).
Refer to HTTP Header Support > Overwriting the Standard HTTP Headers for more details on header roles.

client_host Provide the client host in a header <http header name> instead of X-Sender-Host.
client_service Provide the client service in a header <http header name> instead of X-Sender-Service.
correlation_id Provide the correlation ID in a header <http header name> instead of X-Request-Id.
transaction_id Provide the transaction ID in a header <http header name> instead of X-Transaction-Id.
passthrough Pass a present header <http header name> to the called service.
passthrough= <request header name> Pass an incoming header <request header name> to the called service under the name of <http header name>.
This is equivalent to renaming a header.

Only one value is supported (no multi-value header).





None No header generated.

MD5

Ssl Verify Host
(sslVerifyHost)

Whether to verify the host information form the SSL connection.

On Verification on (default).
Off Verification off.
Existence Limit verification to the mere existence of the host.
Ssl Verify Peer
(sslVerifyPeer)

Whether to verify the peer information from the SSL connection.

On Verification on (default).
Off Verification off.

If you set this header manually, the new header will be send to the target URL. Nevertheless, the correlation ID logged to the transaction log will still be the one generated by the Runtime!
