Problem: When you try to uncompress or compress a large file (e.g., 8Mb or more) using WebShell3 in the H-Sphere Control Panel, the file is not completely uncompressed and WebShell3 seems to hang. IXWebHosting is one hosting service that uses H-Sphere.
Solution: The uncompress or compress function takes a while. Apparently the Internet browser (e.g., Microsoft Internet Explorer) times out waiting and closes the connection. WebShell3 probably interprets the loss of connection and aborts the operation. A work-around is to increase the keep-alive timeout value in IE, which defaults to 1 minute.
See Microsoft knowledgebase article 813827 (http://support.microsoft.com/kb/813827/). You must use RegEdit to add two values to the regristry:
HKEY_CURRENT_USER -> Software -> Microsoft -> Windows -> CurrentVersion -> InternetSettings
KeepAliveTimeout DWORD value 180000 (in milliseconds)
ServerInfoTimeout DWORD value 180000 (in milliseconds)
The above values represent 3 minutes. If you’re working with even larger files, you may want a longer timeout.
I found that 3 minutes works, but WebShell3 may still not respond to display a successful completion. However it appears files are indeed completely uncompressed or compressed. You merely have to refresh WebShell3’s directory view to see them.
