want safari to open pdf file automatically (in browser) without any intervention so i can get back after read it.

i use a web application where i put some pdf for my users.

The probleme is when i click a pdf, it open in other apps, and then i have to close this apps and re open safari.

Is there a way y=that i can use sdafari or another browser to allow me to open pdf in browser so i can click back and return to my Web app.

Thank you
