Hi Renaud, This is a very interesting idea and I think it would certainly be worth adding.
Let me just add some comments: * Could you file a new issue for this extension instead of using SLING-3, thanks. * You should set the response header early in the request, because the response might already be committed at the end of the request and the header may not get through * I would prefix the header name with "X-" to mark it as a non-standard header * I would make the root location for the persistence configurable (using @scr.property tags). A default location would be below /var, eg. /var/log/requestprogress * The same holds for whether to persist or not. OTOH assumming persistence in case of enabled debug log seems reasonable. * Maybe you might want to consider creating a a log structure, because you would be prepared to log a whole lot of logs. Looking forward to see a patch.
