Re: How to hook end of POST

[Thierry Boileau]

Mail sent on the 09/10 and apparently lost. --- Hello Kenji, I'm a little surprised by the fact that the Filter#afterHandle method does not work as expected. What kind of filter are you suspecting to fail? Anyway, I send you a sample code containing 3 classes: an application, a resource and a filter. The application puts the filter as its own root restlet, thus the afterHandle method of the filter is called after all methods. Please feel free to detail your need, I may have missed something. Best regards, Thierry Boileau -- Restlet ~ Core developer ~ http://www.restlet.org Noelios Technologies ~ Co-founder ~ http://www.noelios.com Hi, I'm trying to hook the end of POST calls, and I've tried these : Filter#afterHandle Handler#handleXxx Application#handle Works fine for GET requests, but for POST requests, these get called before response data is sent to the browser. Is there any way to hook the point when response data is sent? Thanks, Kenji Tayama
