Problem with custom http header
Hello
this is continuation of the https://forums.ext.net/showthread.ph...om-HTTP-header
Code is taken mostly from here too
The problem is that http header is sent in all cases, except when using Directevent ( see the submit button below)
means - the setupCrlf function is called, but the custom http header is not even visible in network nebugger, so not on server then too
The only reason for using direct event is the file uploader
So is there a way how to pass the custom header with direct event ( or alternativelly use file uploader with static direct method?)
Thanks
