bill there are other proxies not made by Microsoft Employees, however
Eric is a very helpful guy, and he has indicated that it is difficult
for him to manoeuvre within the confines of Microsoft legal, and so
the tool remains free, and as open as possible - in fact you can code
within in using .NET (which incidentally is a cross platform
technology thanks to Novell and Mono) so you are free to extend
fiddler as you like, while the support comes from Eric should you need
it, not from Microsoft.
As for your actual problem, I am still a little bit surprised you
haven't taken the point: that a mimetype is little more than a string
of text sent by the browser, it doesnt mean it _is_ a jpeg - oh that
life were that simple.
I obviously don't want to beat you over the head with this, but you
are on a journey of discovery and why not just take the advice of the
newsgroup you post on. Steve and I are looking out for you. If you
want to allow image uploads, then make sure they are images, after all
if you receive a brown box with "this is your cd from amazon" you dont
get happy 'til you've opened it, checked its not broken, played it and
it is what you paid for.
Who told you in the first place that mimetype checking was the way to
go, and why believe them over us, email me your url if you need proof,
I'll leave a helloworld.txt file in the doc root of your site. (white
