Class Description

TXUrl(TString Urls) : fIsValid(kTRUE)
 A container for multiple urls.
 It creates an array of multiple urls parsing the argument Urls and
  resolving the DNS aliases

 Urls MUST be in the form:

    root://[username1@]server1:port1[,[username2@]server2:port2, ... ,

 Using the method GetNextUrl() the user can obtain the next TUrl object pointer in the array
 (the array is cyclic).
 Using the method GetARandomUrl() the user can obtain a random TUrl from the array


TUrl* GetNextUrl()
 Returns the next TUrl object pointer in the array.
 After the last object is returned, the array is rewind-ed.
 Now implemented as a pick from the tmpUrlArray queue

void Rewind()
 Rebuilds tmpUrlArray, i..e the urls that have to be picked

TUrl* GetARandomUrl()

void ShowUrls()
 Prints the list of urls

void CheckPort(TString &machine)
 Checks the validity of port in the given host[:port]
 Eventually completes the port if specified in the services file

Bool_t ConvertSingleDNSAlias(UrlArray& urls, TString hostname, TString fname)
 Converts a single host[:port] into an array of TUrls.
 The new Turls are appended to the given UrlArray.

void ConvertDNSAliases(UrlArray& urls, TString list, TString fname)
 Given a list of comma-separated host[:port]
 every entry is resolved via DNS into its aliases
 The parameter is overwritten with the processed data
