Task breakdown
l
The HTTP Server Input task receives a request through the /getinvoice HTTP Action.
Because this task either returns an HTML page with an error message or a PDF, the
MIME type is Auto-Detect.
l It checks whether the invoice request exists by checking if the size of the file is less than
1kb using "File Size Condition" on page478. The condition returns "true" if the file is not
found:
c:\PlanetPress\archives\pdf\invoices\xmlget('/request[1]/values[1]/invoicenum
[1]',Value,KeepCase,NoTrim).pdf
Here, the xmlget() function grabs the invoicenum variable from the GET request, which
would be INV999999.pdf in the specified folder.
l If the file is not found, then a simple, basic HTML page is created indicating the invoice
was not found. For this, a "Create File" on page312 task will suffice, followed by the
"Delete" on page652 output task. As mentioned in "HTTP Server workflow" on page279,
deleting the data file only means you are not doing anything with it locally - it is still
returned to the client.
