addHTTPHeader

scrapeableFile.addHTTPHeader( String contentType ) (enterprise edition only)
Description
In certain rare cases it may be necessary to explicitly add a custom header to the POST data of an HTTP request. This may be required in cases where a site is using AJAX, and the POST payload of a request is sent as XML (e.g., using the setRequestEntity method). This method must be invoked before the HTTP request is made (e.g., "Before file is scraped" for a scrapeable file).
Example
// Add a new HTTP Header to the POST entity to XML.
scrapeableFile.addHTTPHeader( "OBPostReq", "true" );
