new request. This should be put at 0 in order to process requests as soon as possible,
meaning immediately.
And finally, the HTTPServer Input task properties. While these are described in the "HTTP
Server Input" on page220 task properties page, here are a few considerations to keep in mind
when using this task:
l The HTTPAction corresponds precisely to the name immediately following the first slash
of your address. That is to say, placing the action myaction here means the process
would be triggered by opening http://127.0.0.1:8080/myaction in your
browser.
l The HTTPservice accepts both POSTand GETrequests. Other than the presence of file
attachments, there is little difference in how these are handled. This means that visiting
/myaction?id=12345&q=test would be the same as having a form with two <input>
fields named, respectively, id and q, and submitting them with the information
"12345"and "test". In both cases, this information is located in the XMLenvelope that is
the original input file.
l When doing POSTrequests and uploading files, always make sure to include the
"multipart"option in the <form>tag:
<form action="http://127.0.0.1:8080/myaction" method="POST"
enctype="multipart/form-data">
Otherwise, file attachments will not be received, only their file names.
l The Mime Type option is better left at Auto-Detect unless the process requires it to be
forced to a specific type. This means that if a process can either return a PDF when
successful or an HTMLpage with an error message, it will not attempt to send an HTML
with a PDFmime type (which, obviously, would cause confusion).
l
There is no HTTPServer Output task (see below on how to end your process)
Request/Process/Response cycle
Once a process using the HTTPServer Input task is created, it is important to understand the
cycle that is triggered when such a process runs. Note that this is the process when the default
HTTPServer Input task options are used (more on how that behavior changes later):
1. A request is received by the HTTPservice.
2. This request is converted into an XMLrequest file along with one or more attachments
when present.
