HTTP Element Attributes

The attributes of the HTTP entry have the following meaning:

method

The HTTP method with which the request was made. In our case usually POST. This is equivalent to the value of the CGI variable REQUEST_METHOD.

url

Designates the base portion of the URL. Parameter values are not included (see pathInfo and queryString).

pathInfo

Contains the additional path information given by the client. This consists of the trailing part of the URL after the ISAPI DLL name, but before the query string, if any. Corresponds to the CGI variable PATH_INFO.

queryString

Contains the information that follows the first question mark in the URL Corresponds to the CGI variable QUERY_STRING.

remoteAddr

Contains the IP address of the client or agent of the client (for example gateway, proxy, or firewall) that sent the request. Corresponds to the CGI variable REMOTE_ADDR.

Request Transport Example

The following is a sample Transport Info structure adhering to the above schemas:

<HTTP method="POST" url="/soapendpoint/I3SOAPISAPIAD.DLL" pathInfo=""

queryString="" remoteAddr="127.0.0.1">

<Header name="Host">localhost</Header>

<Header name="SOAPAction">"uri:my-soap-request#MyMethod"</Header>

</Headers>

</HTTP>

</TransportInfo>
