Hi, I develop a module that has a ashx file that handle images upload by ajax calls. When I call it the first time the handler get a request that has not the data I that I send it but in the next calls it get the the correct data, but when I do some navigation in the page or do some page postback it redirect me to login again. I think that the first call receive some authentication request and when it is handler by my ashx it break the session login and made that dotnetnuke to reuquest login again. Is there any setup that I need to do for make the handler no break the login session?, maybe some attribute definition in the handler class?
