Hi,

My team is trying to connect with a secure internet directory contents in classic ASP code. The FTP is connecting with user name and password. but it takes a lot of time (15 minutes) just to download a simple xml file. if i access the same directory with IE browser. it asks user name and password and when i enter it it logs in the directoy and shows the directory listing. if i then download a file from IE it takes only 5 seconds to download 70KB XML file. so the question why the classic ASP code taking so much time.

one thing that is the directory contains a lot of XML file around 800,000 so when i connect with IE to the directory then it takes a lot of time displying the whole directory contents. IS IT THE CASE with FTP connection in ASP code that it is also downloading that directory contents.

ASP code is give below

' Build our ftp-commands file
Set objTextFile = objFSO.CreateTextFile(Server.MapPath("test.ftp"))

objTextFile.WriteLine "lcd " & Server.MapPath(".")
objTextFile.WriteLine "open " & ftp_address
objTextFile.WriteLine ftp_username
objTextFile.WriteLine ftp_password

' Check to see if we need to issue a 'cd' command
If ftp_remote_directory <> "" Then
   objTextFile.WriteLine "cd " & ftp_remote_directory
End If

objTextFile.WriteLine "prompt"

' If the file(s) is/are binary (i.e. .jpg, .mdb, etc..), uncomment the following line
  objTextFile.WriteLine "binary"

' If there are multiple files to put, we need to use the command 'mput', instead of 'put'
If Instr(1, ftp_files_to_put, "*",1) Then
   objTextFile.WriteLine "mput " & ftp_files_to_put
Else
   objTextFile.WriteLine "put " & ftp_files_to_put
End If

objTextFile.WriteLine "bye"

objTextFile.Close
Set objTextFile = Nothing

' Use cmd.exe to run ftp.exe, parsing our newly created command file
strCMD = "ftp.exe -s:" & Server.MapPath("test.ftp")
strTempFile = "C:\" & oFileSys.GetTempName( )

oFileSys.copyfile ftp_address & ftp_remote_directory & ftp_files_to_put , "c:\1011.xml"

And, if you run this straight from the command prompt, is it faster that ASP?

ftp.exe -s:path/test.ftp

I would consider this to be the cause of the performance issue.

In any case, if you want to test with an FTP component (free version available):

Can you give me an explanation of the C grade?

As stated here:
https://www.experts-exchange.com/help.jsp#hi73

C: Because Experts' reliability are often judged by their grading records, many Experts would like the opportunity to clarify if you have questions about their solutions. If you have given the Expert(s) ample time to respond to your clarification posts and you have responded to each of their posts providing requested information; or if the answers, after clarification, lack finality or do not completely address the issue presented, then a "C" grade is an option. You also have the option here of just asking Community Support to delete the question.

Considering you did not ask for clarification, I'm not sure why you gave that grade. Also note, other Experts may be reluctant to answer your questions after reviewing your profile if they see you clearly do not understand how EE operates. Please take time to familiarize yourself with that help page.
