First thanks for WinSCP and this support forum. In regard to issue we're experiencing...
Local OS is Windows 7
File protocol = FTP, no encryption
HTTP proxy employed
All other configs are WinSCP default
Receiving server spec - Serv-U 18.104.22.168 on Windows Server 2008
Issue we are experiencing is that for approximately 1 out of 4 files transmitted, the file received on the server side does not contain the data in the file transmitted from the client side. Instead, a file is created that merely contains what appears to be HTTP header text. Below is an example:
GET / HTTP/1.1
Accept-language: en, *;q=0.7
User-Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; InfoPath.1; .NET CLR 2.0.50727; .NET CLR 1.1.4322; MS-RTC LM 8; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729)
Attached is a segment from server log where we captured the issue. 7 test files transmitted in succession, no variation in user action. All files identical, only different is file names. File '*test4' produced the issue, no others did.
Would be grateful for any suggestions on how to prevent this issue.
