I will try to explain you in more details.
Session Vs Cookies
1) Session objects are stored in server memory e.g IIS memory on the other hand cookies stored at client machine.
2) Now when it is stored at client machine then we can have some concerns like
security, cookieless browser, user delete the cookies etc...
3) Issues with Session is, if your server goes down then you loose the session value if you are using inproc session mgt.
4) Session can not be used in case of web farming (Load balancing)
SO now it is upto you as application arch, where you want to store....And if you need more information then google it...Session Vs Cookies....
Thanks

thanks for reply ...its very clear
its new thing i learnt that " session cannot be used in webfarming "<--can i know why? then only way to solve the issue then is to use cookies?
i want to make my question once again clear that i am asking when to use what ,
may be some realtime scenarios if possible or what tradeoff or tips we can use for making a balanced application .maybe like what data can be used for sessions data and what data can be used for storing in cookies?
anyone more who want to share your views more about when to use cookies and when to use sessions are please welcome to write it down here......
thnks for your effort and time in advance

What do you mean with 'launch' the pdf file?? Do you want to open it?? And do you want to open it server side, or client side??
I reckon you store the byte[] in a file and link to that file using a hyperlink...

thanks.
lauch mean i have to provide the option to save or open the pfd file which will create from the byte[].

hi...
how can i redirect to desired page after forms authentication is successful from the login page instead of redirecting to "default.aspx" which my application is redirecting to?
thanks for help in advance.

i am not very experienced in ASP.NET but what i would do is put the redirecting code in the pageload event of the default.aspx page. so, when a user is redirected from the login page to the default.aspx page, the code can determine where to redirect the user according to the information stored in the authentication cookie.
hope this helps.;)

thnks for help in advance

for example you have a page called "abc.aspx" which user should do login here...ok?
you need another page called "def.aspx" to appear after the user have login.
So you need to define a bool variable forexample " check " ...
then set the check ( boolean ) with ur login statement ( checking user name and password ) ...then if the "check" is true then u need to have a code there to redirect to "def.aspx"

thnks for suggestion
sorry ,may be i am not clear or not able to understand what you explained me.
but as u know once we turn on the forms autenticaion as successful
FormsAuthentication.RedirectFromLoginPage(userid, True)
then it redirects to "default.aspx" so we have no chance to redirect to desired page using response.redirect or any other way.
can u please explan me clearly your logic or procedure ..you may write a dummy code if u wish
thnks a lot
