Hi,

You will get all these answers in SAP help

In http adapter addressing type is when we use http destination option rather than url address?

--> Its almost same to put the url in CC or maintain the destination.

Maintaining HTTP destination is easy and allow the quick change to maintain it in SM59. If you have a landscape with test, Q and P systems it can be basis work to configure the destinations in all the systems.

What is HTTP proxy host? What is HTTP porxy port? Where we will define these things? What is the need of these?

--> whenever you need to go outside the firewall, the communication is prefered via Proxy server where partially it will be within and outside the network and will allow the scope to smooth transition of messages. also Proxy logs will help to keep more trace. The below link will provide you the details.

Refer - http://help.sap.com/saphelp_nw04/helpdata/en/4b/e6c2c93b39dc48bbea602cd38e92a0/frameset.htm

What is the difffernce between use logon data for SAP system, use logon data for NON-SAP system, anonymous log on?

--> While defining the HTTP Communication channel, you need to provide

logon data for SAP system -- In case of connectivity with SAP system

logon data for NON-SAP system-- In case of connectivity with NON-SAP system

anonymous -- Anonymous login (i.e. no specific user credentials are required..less security)

What is Header fields?

--> Header Fields are used to provide receiver-specific protocol. They define various characteristics of the data that is requested or the data that has been provided.

HTTP header fields include general-header, request-header, response-header, and entity-header fields.

i.e. you will be specifying as HeaderFieldOne, .... HeaderFieldSix etc.

In additional query string attributes, what is message id, and queue id where we will get this details? What is the need of these

--> You can pass the Message ID and Queue ID details as part of Query string. This normally required in case of maintaining the trace for the particular call. These will be added at runtime. You just need to select the check box.

What is xi payload manipulation? what is xml code parameter?

--> XI Payload by default will be in UTF-8 format, but this can be parsed to other encoding format such as UTF-16 etc.

What is prilog?

What is epilog?

For Prilog & Epilog Refer SAP help for HTTP adapter

Hi,

>In http adapter addressing type is when we use http destination option rather than url address?

Destination is easier to maintain for basis without PI knowledge

What is HTTP proxy host? What is HTTP porxy port? Where we will define these things? What is the need of these?

A proxy is routing a http request to another host. Used for security reasons

>What is the difffernce between use logon data for SAP system, use logon data for NON-SAP system, anonymous log on?

anonymous: No user, no password

SAP: assumedly the adapter transfers the user to capitals

>What is Header fields?

Query string attributes

>In additional query string attributes, what is message id, and queue id where we will get this details? What is the need of these?

PI gives each message a unique Message ID, each queue has as well an ID

>What is xi payload manipulation ?

Change the content of a message

>what is xml code parameter?

how to encode characters

>What is the check box mask special charaters (URL escaping)?

Masking of Control charcaters like < or &
