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 page423. The condition returns "true" if the file is not found:
c:\PReS\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297 task will suffice, followed by the "Delete" on page544
output task. As mentioned in "HTTP Server workflow" on page221, deleting the data file only
means you are not doing anything with it locally - it is still returned to the client.
Tip: Instead of creating a web page from scratch, you could create a web page from a Con-
nect Web template; use the "Create Web Content" on page516 task.
