Hi Boris,
I tried with your code but I got into other problems so I made a search on the internet and finally I got it. In this way it works fine
Function GetFileFromUrl
Lparameters lcRemoteFile, lcLocalFile
Declare Integer URLDownloadToFile In urlmon.Dll;
  INTEGER pCaller, String szURL, String szFileName,;
  INTEGER dwReserved, Integer lpfnCB

DECLARE integer DeleteUrlCacheEntry in wininet.dll ;
	String lpszUrlName 

	=DeleteURLCacheEntry(lcremotefile)

Return URLDownloadToFile (0, lcRemoteFile, Iif(Empty(lcLocalFile), JustFname(lcRemoteFile), lcLocalFile), 2, 0) = 0
thank you all
