Important Configuration, Setup and Options
Before starting to work with HTTP workflows, there are a few key points to keep in mind in
terms of configuration. First of all, the following options are available in PReS Workflow
Preference screen, under the HTTP Server Input 1 and HTTP Server Input 2 sections:
l
Port (default value: 8080 recommended): The port number is the one in which a
browser needs to make a request to PReS Workflow. By default in most web server, port
80 is used and, when this is the case, it is not necessary to include it. For example, if I
type http://www.objectiflune.com/ in my browser, it is actually accessing the address
http://www.objectiflune.com:80/ , but port 80 is always hidden. The reason port 8080 is
used by default is to prevent any interference with existing web servers installed or
activated on the same server as PReS Workflow.
l
Time-out (seconds): This determines how long the HTTP Server service will wait for the
process to finish, before returning a time out error back to the client browser. This means
that if a process takes more than 120 seconds (by default) to complete, the browser will
time out. While you can change this value, it is recommended to always keep your
processing to a minimum, since both browsers and users generally frown upon being
stopped for more than a minute, unless they are well aware of this processing time (and
even then...)
l
Enable server for SSL requests: This enables secure communication between the
browser and the server via HTTPS. By enabling this option, you will need to provide for
the proper certificates, key and password. While this configuration is beyond the scope of
this document, there are plenty of resources on the Internet to explain these systems.
l
Serve HTTP resources: This is where you enable static resources in PReS Workflow.
When enabling this option, the HTTP server will always look in the Resource Folder for
files requested inside of the Resource action name as a folder. This means that, if your
Resource folder is c:\PReS\http and your Resource action name is static,
pointing your browser to http://127.0.0.1:8080/static/css/style.css will
immediately load and return the file c:\PReS\http\css\style.css . This does not
require any process to work - everything is handled directly by the HTTP Server Input
and files are returned immediately. This feature is very useful when dealing with
stylesheets, images, browser JavaScript, or static html files that do not require any
processing.
