Then if you don’t have the internet library (libURL) included you need to include it as an extra inclusion. tsNet is resolved as a dependency of libURL. At the moment we don’t have a facility for turning tsNet off in the event you want to use libURL (not really sure why you would want that but I guess it’s possible). You can turn tsNet off if you want to with `dispatch “revUnloadLibrary" to stack “tsNetLibURL”`

To add to what Monte has said, the tsNet external wraps around the 
existing libURL library as well as providing its own set of commands and 
functions.  This provides two ways of using the external.

Using the standard networking commands (put x into URL y, post x to URL 
y, load URL x, etc... ) will now automatically use the tsNet external in 
DP3 when using the internet library.

There are a quite a number of benefits of tsNet, however the four most 
obvious benefits you will see by using it in this fashion are:

1.  you can use SFTP URLs in the format of 
"sftp://user:pass@host.domain.com".
2.  multiple asynchronous requests to the same server (for example when 
using "load URL x" commands) are processed immediately rather than 
sequentially as would happen previously
3.  a significant performance improvement particularly noticeable on 
large file transfers, or when executing multiple requests to the same 
server one after another
4.  all processing of data is offloaded to the external, improving 
responsive of the LC application to other tasks during transfers (for 
example, other handlers being triggered)

However, this only gives you access to a subset of the features of the 
tsNet external.

There are a range of commands and functions available in the tsNet 
external, all starting with "tsNet", that can be found in the LC 
dictionary.  These give you access to the additional features like 
sending e-mails via SMTP(S) and comprehensive asynchronous request types 
that are not available using the standard internet library (for example, 
firing off multiple HTTP POST requests asynchronously).

I will be adding more documentation and examples over the coming weeks 
to assist with using this external.  In the mean time, I have uploaded a 
very simple sample stack that demonstrates how to send multiple HTTP 
POST requests in an asynchronous manner here:

Hope that helps,

Charles
