Basically thinking out loud. So here you'll get the condensed version. Basically doing something like ``` $ find . -name "*.java" -exec grep -H "httpClient" {} \; ``` and all other possible httpclients I could think of, I found no example of an outboud HTTP connexion from guacamole. So as far as I can see we are free to implement this how we want. However it needs to - No introduce any new large dependencies to guacamole - treat both POST and GET requests - Be relatively clean java.nat.httpUrlConnection is a bit old and ugly, but I couldn't find and apache commons I/O function that treated both POST and GET. The slightly more modern java.net.http.httpClient will make the code cleaner. Don't see the point of using org.apache.http.impl.client.CloseableHttpClient as the htpp post/get operations are one off each time. I've updated the code using httpClient and included asynchronous operation to release control back the the Tomcat Servlet so as not to impact the rest of guacamole if the operation takes some time. If you prefer a different http client then sure I'll change it. Now is the time to complain as this is the first outbound connection in guacamole, so getting it right before introducing code we might regrets is the right time to do. :-) -- This is an automated message from the Apache Git Service.
