ASP.NET and non-unique Session IDs Paul Watson3-Jul-02 3:57 Paul Watson 3-Jul-02 3:57  Can anyone coroborate a mad client of mine who swears that MS themselves say that Session IDs can sometimes not be unique between active visitors to a web-app? Session.SessionID <--- that one I can maybe understand problems creeping in when IIS is being hammered by hundres of thousands of visitors, but this site in question is used by at most three people at a time. thanks regards, Paul Watson Bluegrass Cape Town, South Africa The greatest thing you'll ever learn is just to love, and to be loved in return - Moulin Rouge Michael P Butler wrote: Some people fantasise about "real people", others about celebs Re: ASP.NET and non-unique Session IDs Michael P Butler3-Jul-02 4:16 Michael P Butler 3-Jul-02 4:16  The only thing I'm aware of is this little bit from MSDN You should not use the SessionID property to generate primary key values for a database application. This is because if the Web server is restarted, some SessionID values may be the same as those generated before the server was stopped. Instead, you should use an auto-increment column data type, such as IDENTITY with Microsoft® SQL Server, or COUNTER with Microsoft® Access. which makes sense, but it wouldn't make sense to not have unique session id's whilst the server was running. Unless it's a bug of course.

As for the bug bit, that is what the client is ranting and raving about. We used .NET, but I hardly think even MS would have created a system like ASP.NET which results in non-unique SessionIDs on a low-load app. I can get 10 000 users at once may cause ASP.NET to drop it's pants, but not 3. Thanks.

The only issues I've ever heard of regarding ASP Sessions are the session cookie hashes being sniffed over the network.

Re: ASP.NET and non-unique Session IDs Jeremy Falcon3-Jul-02 5:57 Jeremy Falcon 3-Jul-02 5:57  I haven't used ASP.NET, but with ASP the Session object relies heavily on cookies to operate. So, this could be a logical conclusion, but personally I haven't seen it happen yet. If you do have any more info about this, could you please let me know as I am in the middle of rapping up a web app written in ASP that uses this? Jeremy L.

I have a button message that I catch with vb script, and I want to just open a html site in a seperate browser instance. I am new to vb script, so any advice would be great! Thanks in advance! Re: How can VB script be used to open a web page in a seperate browser window?

My ISP would not allow me to run a component in their server. I must use Javascript or VBScript in my ASP to do this kind of work. Does anybody know how to do it? Sample code will be much appreciated! TIA! Re: Automate thumbnail creation Chris Rickard1-Jul-02 4:09 Chris Rickard 1-Jul-02 4:09  You're probably out of luck... If the server runs .NET you could use GDI+ to do this if not ASP3, JavaScript, and VBScript do not have that functionality built in and must use a COM component. Re: Automate thumbnail creation Nnamdi Onyeyiri1-Jul-02 10:15 Nnamdi Onyeyiri 1-Jul-02 10:15  if the images are too big, you can get the script to show the pics at thumbnail size, using the HTML code that is output.

One great thing about .NET is the xcopy deployment capability, just drop your component into the bin folder. If your not using .NET I'm sorry I can't help. IIS and TFTP? Jörgen Sigvardsson30-Jun-02 20:52 Jörgen Sigvardsson 30-Jun-02 20:52  Can anyone explain to me why IIS always start about 10 tftp.exe processes sunday night? Two sundays ago, these processes wanted to access the internet. Of course I told my firewall to say NO. Last sunday tftp wanted me to insert a disk in my cd reader. This is starting to piss me off! I rule my machine, not vice versa. Sonorked as well: 100.13197 jorgen FreeBSD is sexy. Re: IIS and TFTP? Chris Rickard1-Jul-02 4:06 Chris Rickard 1-Jul-02 4:06  TFTP is not a standard component of IIS. Either a 3rd party program has installed a TFTP program and is misbehaving or you've got yourself a virus. Re: IIS and TFTP? Roger Wright1-Jul-02 12:58 Roger Wright 1-Jul-02 12:58  That's interesting... I just checked my server. In C:\Inetpub\Scripts there were 373 files titled "TFTP####" where "####" are decimal digits. All were read-only, all were empty. TFTP.EXE does exist on this machine, dated the day I installed Win2K, and the system was just scanned for viruses two hours ago, so a virus is unlikely. But I do wonder where these files came from... I've deleted them I'll let you know if anything breaks... I Drowned Schroedinger's Stupid Cat! Re: IIS and TFTP? Chris Rickard1-Jul-02 14:07 Chris Rickard 1-Jul-02 14:07  Oh yeah I remember now! Sorry guys, time to update your virus scanners and goto Windows Update. You've been hit with NIMDA. Re: IIS and TFTP? 1-Jul-02 14:43 1-Jul-02 14:43  I know your problem, indeed it's persons from warez teams that use tftp to get file on their machine and send u an ftp server in order to use your pc to stock it some warez stuffs.
