Can you provide a clearer definition of "unregistered user". By what means are you trying to identify users? Is it by some session identifier you provide to the browser? Does each user provide a userid and password instead?

unregister user mean any one who visit website first time.mean to say never registered or fill signup page on my website.i think now you understand.and yes i manage sessions.only registred user provide userid and password

This is the whole point. Simon and I tried to explain why this is impossible. During one session this is trivial, but when a session is closed and open again, there is no a valid way to tell if this is the same user or not without login.

As SA has put it there is no way to effectively control the number of downloads that they can do without having them register on your site.

you have to options that you can use

1. IP Addresses that the client visits your site

but not all Internet connections used fixed IP's so more than one person can use the same IP address

2. Cookies

This writes something in the users temporary Internet directory and you can check / read from it. BUT the user or AV Suites can remove this from the computer.

Quite correct, and very good clarification about possible ways to identify the user, my 5.
Unfortunately, OP gets stubborn about the topic and insist that I did not understand the problem, confessed he voted 1 for my answer, maybe your one, too. I tried to explain again but don't know if it is possible or not. There are people who think that their "requirements" should be met only because they require them. :-)

Thanks SA :) I read his responses and have the same feeling about his stubornness to realise what he is after can't be achieve with out asking the user to supply some level of information directly or indirectly (which is honestly isn't very effective)

Sergey Alexandrovich Kryukov 5-Oct-11 11:48am

Exactly.

Solution 1

If you use no login you have no way to identify your user. You can only remember client's IP, but it can be the same for more then one user or different for the same user, changing from time to time, etc. I would say: forget the idea. Either use authentication of the users or allow unlimited downloads.

i need that any one can download only one file without login mean to say unregistered user can download one file.and if he want more then one file to download then he must sign in as a register user and download upto 10 books per day.i think now you can understand

Sergey Alexandrovich Kryukov 5-Oct-11 2:03am

Who cares what do you think you need? I explained you why you cannot implement that, period.
If you find a mistake in my considerations, be so kind to tell me about it.
Just curious: did you vote 1 here? Would be interesting to know why...

genious Developer 5-Oct-11 3:45am

dear SAKryukov you answer is not according to my question.why i implement as you say.i want to implement the changes as i needed.so i ask question here.so how can i rate you more then 1 as your answer in not accoding to my question????

Sergey Alexandrovich Kryukov 5-Oct-11 8:01am

The answer is not according your question because your question is incorrect. You and only you are responsible for this failure. Your requirement is logically incorrect, and your acceptance to the answer is mistaken to say the least.

genious Developer 5-Oct-11 8:06am

dear SALryukov donot blame on me i think you are enough mature.how you say my reqirements are incorrect and logically incorrect.if you did not understand what i want then donot answer.i saw many time the same thing implemented which i need.

Sergey Alexandrovich Kryukov 5-Oct-11 9:26am

If I really don't understand, this is my fault, but I don't see your explanation of what I don't understand. You just said: "I need that any one can download only one file without login mean to say unregistered user can download one file; and if he want more then one file to download then he must sign in as a register user...". Here is the problem: when a user is not registered, you have no criterion of the notion of the "same user". Anyone can restart session (say, close browser and run it again) and after that moment you have no way to know if this the same user as a second ago. Now tell me where I did not understand you.

Sergey Alexandrovich Kryukov 5-Oct-11 11:56am

By the way "i saw many time the same thing implemented which i need" need some evidence. I don't believe you could see it. It could look similar, but I already explained why what you need is not possible. Anyway, I would appreciate if you post a link on what you observed. (And look more thoroughly by yourself.)

(And please leave me the liberty to decide when to post my answer or any other post and where not to -- thank you very much.)
Cheers,
