The inputs of a web application are detected through a technique such as crawling, and then the characteristics of the inputs are determined. The characteristics are determined by identifying how the inputs react to various probes containing varying characters and varying numbers of characters. As such, the characters allowed by the input are identified, the maximum and minimum number of characters that are accepted and the manner in which the characters are treated by the web application. Further characteristics of the inputs are determined by examining the context of the inputs, the markup language associated with the input, the size of the input, etc. The knowledge regarding the input characterizations can be applied in a variety of settings.
