+## About parameters
+Note that by default there is a smart computation for the query/post/... parameters:
+for instance
+- `q=a&q=b` :  will create a **WSF_MULTIPLE_STRING** parameter with name **q** and value `[a,b]`
+- `tab[a]=ewf&tab[b]=demo` : will create a **WSF_TABLE** parameter with name **tab** and value `{ "a": "ewf", "b": "demo"}`
+- `tab[]=ewf&tab[]=demo` : will create a **WSF_TABLE** parameter with name **tab** and value `{ "1": "ewf", "2": "demo"}`
+- `tab[foo]=foo&tab[foo]=bar` : will create a **WSF_TABLE** parameter with name **tab** and value `{ "foo": "bar"}` **WARNING: only the last `tab[foo]` is kept**.
+
+Those rules are applied to query, post, path, .... parameters.
