Erel B4X founder Staff member Licensed User Longtime User Nov 15, 2012 #1 This question is about HttpUtils2: HttpUtils2 - Web services are now even simpler In some cases we need to modify the request. For example we may need to add a header to the message before it is sent. Code: Copy Dim Job As HttpJob Job.Initialize("Job", Me) Job.Download("http://www.b4x.com") ' ****** The header is set after Download is called ?! Job.GetRequest.SetHeader("User-Agent", "Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; Trident/6.0)") Note that it is not possible to call Job.GetRequest before Job.Download as the request is initialized in Job.Download. Does it work? Why?

Since CallSubDelayed uses the message queue, the service code/sub will not be executed until the current thread exits, which will exit after SetHeader is set, and whenever the calling sub completes. EDIT: Ofcourse, I didnt know this before to ever use it. Good technique, but not so straight forward for readability. Upvote 0

Erel B4X founder Staff member Licensed User Longtime User Nov 15, 2012 #4 :sign0098: You are correct. This is a side effect of CallSubDelayed. CallSubDelayed is used here to call the service from the class. That was quick. Next time I will think of a more challenging question... Upvote 0
