VCheck Proxy Password Prompt


Question:

Ever since the addition of proxy password prompts in VCheck (v 38), I cannot get it to work without editing the file and removing the prompt and related code.

Our proxy server is configured to require passwords for HTTP access, but not for FTP. How is VCheck determining that it needs to prompt for FTP passwords?

Answer:

Note: the WinBatch download sites no longer supports the FTP protocol.

Starting in VCheck version 38, there have been some changes to how vCheck works.

vCheck attempts to access remote files in the following order:

  1. HTTPS
  2. FTPPASSIVE
  3. FTP

Once it determines it is able to access via a certain protocol, it stores that information in a file called update.ini. If you want to force it use the FTP/FTPPASSIVE protocol, you will need to edit/create the Update.ini.

For FTPPASSIVE

[Transfer]
Protocol=4
Proxyinfo=
[Options]
ShowText=0

For FTP

[Transfer]
Protocol=2
Proxyinfo=
[Options]
ShowText=0

Some recent changes include how vCheck handles proxy servers. It determines what to do based on the HTTP error code returned by iHttpOpen(which sends the request to the server).

If the HTTP error is 407, that tells whether proxy authentication is required.

If the HTTP error is 401, that tells whether server authentication is required.
