Major drawback of REST web service
web-services
Solution
REST supports PUT and DELETE methods as well as GET and POST - so if your app should run in a browser you're limited.
The convention is to use GET to retrieve information, POST to create new object/entity, PUT to update an existing object/entity and DELETE to delete...
Problem
I am reading a Javascript book where it talks about web services but I find it hard to understand the following sentence as being a drawback of using REST (Representational State Transfer). One of the biggest drawbacks to using REST is that some browsers support only GET and POST methods, whereas many firewalls allow passage of only GET and POST methods. I don't really see how this is regarded as a drawback. English is not my 1st language so it could be just me finding it hard. Can someone elaborate on this?
