When a client sends a request to the server, it does not have to specify any headers. All those which were specified are placed into this directory. Some headers are repeated, in which case their values can be extracted as follows (using the Accept header as an example):

ServerFind(parcel, "Request:/Header/In/Accept", &header);   // gets the header object
ServerSize(header, &size);                                  // gets the number of headers
ServerReadText(header, "1", buffer, sizeof(buffer));        // retrieves the first "Accept" header
ServerReadText(header, "2", buffer, sizeof(buffer));
etc...

The list provided here is a representative sample of the types of headers that are typically supplied. Please read the HTTP Protocol Specification for a complete list of headers which may be supplied by Web Browsers.

Request:/Header/In/
Setting	Explanation	Default / Example	Data Type	Access R,W,A,D
