How to send a null filename?
I've got a situation where I appear to be falling between two stools.
I have a multi-stage process in a web application which consists of uploading a file and then performing several operations on it. The upload stage is fine - the problem arises with the subsequent stages.
The application, when running via IE. produces the following in its form POST for the second stage:
-----------------------------7dcca18d046a
Content-Disposition: form-data; name="UploadFileControl"; filename=""
Content-Type: application/octet-stream
-----------------------------7dcca18d046a
As you can see, this has a null filename.
I can recreate this in my JMeter test script, and it produces:
--7KuasTCyGRcIVS-GlnO7ypZpVo7IJO5IsBYge2
Content-Disposition: form-data; name="UploadFileControl"; filename=""
Content-Type: application/vnd.ms-excel
Content-Transfer-Encoding: binary
<actual file content, not shown here>
--7KuasTCyGRcIVS-GlnO7ypZpVo7IJO5IsBYge2--
This seems superficially OK, but the problem is that JMeter fails with a file not found exception and thus the sample does not run.
If I remove the null filename, the sample runs, but the web application fails to perform the required operation.
Do you know how I can 'fake' the null file in JMeter, so that it does not throw an exception yet enables the web application to receive the required null parameter?
Thanks, Roderick

Maybe a preprocessor to set the filename header to emtpy string?

As a workround you can provide a file that contains the entire POST
content including headers.
