Hi Jan, This will be fiwed in the next 1.6
- some sample fetches which requires a valid haproxy http transaction, which doesn't exists in Lua land because when the applet start, the transaction is no longer valid are prohibited. - in replacement, a new struct in the AppletHTTP class contains headers and other usefull information. So, for the header you must access to the Lua structs in place of sample fetches, for other things like SSL information you can continue to use the sample fetches (the layer 5 information are available during the applet time).
