I'm reading someone's slides on bypassing WAFs.
&==;: Python Django between parameters;
FooBar==POST verb: Apache with PHP;
<%I%M%U011e>==<IMG>: IIS ASP Classic;
;/path1 ;foo/path2;bar/;==/path1/path2/: Apache Tomcat;
On one page he mentions the string
&==;-. Does anyone know the meaning of "between parameters"?
