One way would be to use C file handling functions to open and modify
the file with the parameters before uploading it. But depending on how
much you need to modify the file (you may have to seek to the right
place in file and then replace/append the parameter) and how many
users will be simultaneously running during the load test, it can
potentially cause too much disk usage on your agent machines.

It may be possible to create a manual web_custom_request using raw
HTTP request. I haven't done it but sounds challenging & fun. You can
use Webscarab to get the raw HTTP request. Basically, the body of the
request will have the contents of the file and will be something like:

-----------------------------25723100747689
Content-Disposition: form-data; name="File"; filename="readme.txt"
Content-Type: text/plain

test
-----------------------------25723100747689--

where "test" is the actual content of the file. Now you can
parameterize it however you want (atleast for ascii files). More info
on HTTP file uploads here: http://www.ietf.org/rfc/rfc1867.txt

Hope it helps,
Gaurav
