I'm doing some testing on my web app with Tamper Data. I've had success with Tamper Data in the past for normal HTTP post requests, but in this particular case I want to modify a post request that that has the content-type set to multipart/form-encoding.
Tamper Data shows this request as one big blog of messy escaped-ness and the text field is too small to view the entire thing or reasonably edit it. I also tried copying/pasting to a text editor, making changes, then copying/pasting back but I must not be doing something right because the web app isn't acting like it's received any form data.
Is there a setting I'm missing to have tamper data modify multipart requests like this in an easier manner? If not, any tips for doing it by hand? Thanks.
