◆ prepareOpenURL()

std::string XrdTpcUtils::prepareOpenURL ( const std::string &  reqResource,
std::map< std::string, std::string > &  reqHeaders,
const std::map< std::string, std::string > &  hdr2cgimap,
bool &  hasSetOpaque 
)
static

Prepares the file XRootD open URL from the request resource, the xrd-http-query header of the HTTP request and the hdr2cgi map passed in parameter

Parameters
reqResourcethe HTTP request resource
theHTTP request headers
hdr2cgimapthe map containing header keys --> XRootD cgi mapping
hasSetOpaqueis set to true if the returned URL contains opaque query, false otherwise
Returns
the XRootD open URL
