To check/show the status, you can use libUrlSetStatusCallback. (see  
the Rev docs for a very basic example).

There is no "official" way to stop a post command. However, you could  
try using the following undocumented command to achieve this:

   ulCancelRequest <url>

For example,

   ulCancelRequest "http://www.somewere.com/mypost.cgi"

This is an internal libUrl handler that is used by the unload url  
routine. The same handler can also be used to cancel "get url"  
requests. ("non-blocking" calls such as "load url",  
"libUrlDownloadToFile", etc can be cancelled by using unload url)

However, if you use it, be aware that it may not always be available  
in future liburl releases (unlikely), or it may get renamed (a little  
more likely). So check that it still works should you upgrade the  
libUrl version used in your app.
