Bertrand Delacretaz commented on SLING-5824:
--------------------------------------------
bq. If the URL is not long we are using GET. If it is very long we can convert
to POST.
IIUC this happens in client code, so what prevents you from handling both GET
and POST in your server-side code?
If that's done at the servlet level for example, that's much more transparent
than a servlet filter manipulating request method names, which adds to the
Mystery Of What Happens Before My Servlet Runs.
> Servlet Filter to do POST tunnelling to GET
> -------------------------------------------
>
> Key: SLING-5824
> URL: https://issues.apache.org/jira/browse/SLING-5824
> Project: Sling
> Issue Type: Improvement
> Components: Servlets
> Reporter: Christanto
>
> Sometimes there is a case where the request URL is very long. For example,
> during advanced search where there are many fields.
> To accommodate this, the request is tunneled through POST, such that the
> client do a POST request and then the server convert it to GET, so that the
> other code in the chain only knows about GET.
> So far the custom POST handler needs to be created specifically for this:
> {code}
> slingRequest.getRequestDispatcher(resource).forward(new
> HttpServletRequestWrapper(request) {
> @Override
> public String getMethod() {
> return "GET";
> }
> }, response);
> {code}
> Since this is generic and to avoid creating a custom POST handler every time
> for this, it makes sense to implement this in Sling using Servlet Filter. For
> example, a special parameter can be introduced for this purpose named
> "\_method\_". So the filter will check for this parameter and wrap the
> request accordingly (also remove the "\_method\_"). This is similar to
> "\_charset\_" parameter for encoding.
