RESTful PUT AND DELETE and firewalls
advertisements
In the classic "RESTful Web Services" book (O'Reilly, ISBN 978-0-596-52926-0) it says on page 251 "Some firewalls block HTTP PUT and DELETE but not POST."
Is this still true?
If it's true I have to allow overloaded POST to substitute for DELETE.
Firewalls blocking HTTP PUT/DELETE are typically blocking incoming connections (to servers behind the firewall). Assuming you have controls over the firewall protecting your application, you shouldn't need to worry about it.
Also, firewalls can only block PUT/DELETE if they are performing deep inspection on the network traffic. Encryption will prevent firewalls from analyzing the URL, so if you're using HTTPS (you are protecting your data with SSL, right?) clients accessing your web service will be able to use any of the standard four HTTP verbs.
