I am unclear on what happens under the covers when a file is uploaded to
a web site. From the Generation Log file, it appears that LoadRunner
reads the file(s) at run time, packages them together, and sends them to
the server as an attachment to a single POST request. Is that right?



My issue is that I need to parameterize some values in the files that
get uploaded. Any idea of how to do that? I could create a large
number of unique files then parameterize the file name in the
web_submit_data, but that is a pain.



Better still, would be if there is a way simply generate a string in
memory them pass it to the POST so that it looks like it is attached as
a multipart/form-data.



This is my captured/modified web_submit_data statement.



web_submit_data("File Uploader",

"Action=http://xyz.com",

"Method=POST",

"EncType=multipart/form-data",

"RecContentType=text/html",

"Mode=HTML",

ITEMDATA,

"Name=file0", "Value=C:\\temp\\CustomerOrder.dat", "File=Yes",
ENDITEM,

"Name=file1", "Value=", "File=Yes", ENDITEM,

"Name=file2", "Value=", "File=Yes", ENDITEM,

"Name=file3", "Value=", "File=Yes", ENDITEM,

LAST);
