For an ASP C# website I made, I have user authentication using the Membership framework with SQL Server as the back end. The only complaint so far is that after a certain amount of time, they get automatically logged out. Is there anything I can do to make sure that users will stay permanently logged in unless they manually logout?
Edit: The webserver is IIS 7.5. I suppose this could just as easily be an IIS question.

The default timeout for session is 20 minutes. If the user takes no action, i.e. refreshing the page or navigating to another one, the server can't tell if they closed their browser, gone somewhere else, or died. You can adjust the timeout via the web.config file but you will still be left with the same problem, just at a later time

I figure setting it to 122 years and 164 days should be sufficient.

Legacy ASP, or ASP.Net? You have to find a 3rd-party library to do what you want.

I actually did just that at one point. I found that the free libraries were crap (didn't render the page as expected). The way I got around it was to use a Windows Forms WebBrowser to render the page (on the server side), render that control to a bitmap (WebBrowser.DrawToBitmap), save that bitmap as a PNG, embed that PNG into a PDF (the free libraries seem to be capable of at least this), then return that PNG to the browser as raw byte data (this will help you figure that out). I also remember having to do some custom HTML parsing to print each page neatly. It's tricky, but can be done (took me 2-4 days IIRC). Google for anything above you don't know how to do (e.g., you can google for free PDF libraries).

Hi All, I am wondering how to validate date using regular expression and not allowing any future date if the user wants to put it in anyway.
thanks,
|
|
|
|
|
Hi,
no, it's not possible with regular expression, regular expression can only validate patterns, you can use compare validator for this purpose or use .NET function DateTime.Now to acquire todays date, then compare it programmatically with the date from user's input.
Regular expression for date is
(?x)(? [1-9]|1[0-2])(/?)(? [1-9]|[12][0-9]|3[01])(\1)\d{4}\d/\d/\d{4}
|
|

|

Thank you Iqbal bhi, I will get the user input and then compare with present date in the back end.
thanks for the date format.
|
|
|
|
|
thanks for your reply, I know it can be done using back end Csharp code. But how do I display message to user that something is wrong.
|
|
|
|

Just to add to Shahriar Iqbal Chowdhury's answer, you can use the regex validator to do an "idiot check" Client side and use dateTime.TryParse[^] to check server side. There are several attempts to do it here[^] without the regex using JavaScript instead.
For the regex pattern, I've always found http://regexlib.com[^] useful, it also gives a summary of how well well the regex matches etc.

I am doing some research into ftp.
I have developed an website that allows the user to ftp files to a server.
I was just wondering if there are any security implications in doing so?
Any information is much appreciated.

You are going to force them to log in ? Right ?
No anonymous connections. You may want to see if there is a method for your FTP server software to limit the amount of data a folder can have uploaded. (Think disk quota)
I would recommend monitoring the FTP destination folder very carefully for abuse; maybe a nightly job that would compare the number of files / size from the night before to the current day and send an email notification if too many files have changed or the file size has changed dramatically. Using a system like this, you won't bother an Admin with yet another email notification.
just some things to think about.
Good luck.

FTP passes login/password in the clear, so someone could intercept them. Use SFTP, if you can.
Naughty people like to find open FTP locations to upload naughty things. Then they tell their friends where to get those naughty things. Make the upload folder write-only. (If you need to have those files accessible via FTP again, you move them to a downloadable folder, after checking them out either manually or by a process you'll need to create.)

I have looked into the SFTP, and the only way of really doing this is using 3rd party component although there are some class librarys. Would another alternative be to use SSL and ftp?

I'm pretty sure once you hit the FTP protocol it's just going to jump out of the SSL world.
|

|
|

Appreciate the info. I'll do some more research and come up with a solution looking into SharpSSH which looks promising.
