Get POST parameter when using BoundaryWebKit



I am trying to retrieve the values of POST parameters with request using BoundaryWebKit. There requests use the header

multipart/form-data; boundary=----WebKitFormBoundaryy4UHhOP6cBZ28APA

The Payload of these kind of POSTs looks like this:

Content-Disposition: form-data; name="DEFAULT_RESOURCE"

Content-Disposition: form-data; name="EXPIREDPWD_RESOURCE"

Content-Disposition: form-data; name="EXPIREDPWD_NOMAIL_RESOURCE"

Content-Disposition: form-data; name="CENSIMENTOMAIL_RESOURCE"

Content-Disposition: form-data; name="WSC_FAIL_REDIRECT"

Content-Disposition: form-data; name="DIGITAL_DEFAULT_RESOURCE"

Content-Disposition: form-data; name="j_username"

Content-Disposition: form-data; name="j_password"

As you can see, it is quite different compared to the standard POST http body.

Are we able to extract the values we need? I tried to set up the Web Request sensor suing wildchar "*" but it seems it is not showing what we need.

Thank you,

We cant extract these values from the HTTP POST Body. The best approach is to try to capture the values you need from a method argument on your server-side code implementation. You can define a custom sensor and then capture method arguments. You can also capture a value in case it gets passed to a method as a complex object.

If you want to learn more about custom sensors check out my youtube tutorial on advanced sensors:


Hi Andreas,

customer doesn't have agents on the backend so we cannot get these information using other sensors. I suppose I am going to open an RFE in order to ask for this feature.

Thank you,
