Re: client holding open a connection
Funky stuff. I always just assumed that the server sends off the content and then closes the response regardless of what the client is doing (otherwise, how would the server know if the client closed the page half way through page load).

Re: Case Sensitive SQL
Thanks Peter, Roger, Claude and Shane :) well I am using encryption and I do agree MS Access is only good for small personal works and not for medium or large scale applications. Besides, I have another small query, when I use the GROUP BY clause with MS Access it gives the error something like 'object overflow'. The query works fine without the GROUP BY clause. It's a simple select query having a where clause followed by an ORDER BY clause but when I add the GROUP BY clause it gives the object overflow error. Even when I write this SQL in MS Access itself, it gives the same error. Does any1 has any idea... is there a problem with my SQL skills or do I just need to change my database ;) If any1 could provide his workable SELECT QUERY with WHERE, ORDER and GROUP BY clause... that would be superb :)) Regards, Arsalan -- From: "Peter Boughton" Sent: Monday, June 15, 2009 11:02 AM To: "cf-talk" Subject: Re: Case Sensitive SQL > > Probably a little over-the-top, but the point still stands. > > MS Access is fine for basic office use, but for web apps you're better off > picking Derby, H2, MySQL, Postgres, etc - or one of the free 'Express' > editions of Oracle or MS SQL Server. > > > More importantly though, I just noticed this is discussing passwords, > which I missed the first time. > > If something is important enough to password protect, then that password > should - at the very least - be MD5 hashed, (if not a more secure salted > SHA hash, or similar). > If it's not important enough for that, just ditch the password altogether. > > And that aside, if the value is user input, use cfqueryparam! > > ~| Want to reach the ColdFusion community with something they want?

RE: scoping
If you don't explicitly assign a variable to a scope, then it's automatically put into the VARIABLES scope. So in your example, you could refer to your var as foo and it would be just fine. Having said that, it's a best practice to explicitly scope your variables to avoid confusion, and potential collisions. andy -Original Message- From: Chad Gray [mailto:cg...@careyweb.com] Sent: Monday, June 15, 2009 9:22 AM To: cf-talk Subject: scoping Say you defined a local variable like this on a CFM page and it returns a query object: Should I write out my variables like this when I out the query object? #variables.foo.goo# Or is this sufficient? #foo.goo# ~| Want to reach the ColdFusion community with something they want?

AW: scoping
Steve, just a quick info here. If you have every variable in the variables scope prefixed with "variables." it is actually slower (factor 2 at least) than if you address it without the "variables." notation. This is valid for Adobe's CFML implementation. In Railo it's indifferent. Whereas inside CFC's the "variables." notation is faster than writing it without the "variables.". My personal recommendation is: Scope everything except the variables scope. And for readability reasons scope queries as well!

In CF Web applications there is only ONE user at a time on the database: ColdFusion. There may be several users in the CF application, but only one in the database: ColdFusion. If multiuser applications are not running properly, the problem is with the way the ColdFusion application is accessing the database file not with the datasource file per se. There is simply NO Access application on the Web, what is called an application is actually the code that makes it running. There is no Access code in a CF application using an Access database, only CF code. So everything you may have heard or read about "Access applications" is not applicable to access datasources under CF. I've been using Access datasources in small/medium application since ColdFusion 1.4, for more than 10 years, and I haven't encountered the slightest glitch imputable to the Access datasource. ~| Want to reach the ColdFusion community with something they want?

Re: Case Sensitive SQL
Right, include all the columns, but also GROUP BY cluster not GROUP BY clust In other words, group on the actual column name, not the alias. Now, if your goal is simply to get only 1 of every record combination, since you're not using any other Aggregate functions besides GROUP BY, why not just use DISTINCT?

RE: client holding open a connection
Ben, I won't claim that I know that much more about server internals, but I do know that the web server doesn't just send the entire response (which could be megs in size) out into the Internet and hope the end computer actually receives it. How would that handle lost or corrupt packets? If you have ever used SeeFusion, you will see it has a "time to first byte" number. Ignoring use of the cfflush tag, if a web page being processed has a TTFB value of 500 ms but the total page time was 10 seconds, that tells you that CF finished its work in half a second, and the first byte of the response went out to the client after half a second. It also tells you the client took 9.5 seconds to finish receiving the response. The client's connection speed is usually at fault. What that tells us though, is that the web server "knows" that the client is still receiving the data, and it re-sends any packets that weren't received correctly. (Once received, all the packets are reassembled on the client to form the entire response) To prove this, download a packet analyzer like WireShark (used to be Ethereal) and hit a web page while capturing. Filter on that TCP stream, and you will see the request headers, and response headers/body. Go back and look at each TCP packet to be sent, and after the initial HTTP GET request, you will see a series of packets coming back from the remote server, after every few packets, you will see an "HTTP [ACK]" begin sent from your computer back to the server basically saying "Hey, I got it!" This conversation of "here you go" and "hey, I got it" continues until the entire HTTP response has been transferred to the client. The final packet has a "FIN" flag which is also acknowledged that states that was the end of the packets. To my knowledge, all of this happens at a pretty low level after your CF code has finished processing. The Java thread is still in use though while the data is being read out of the servlet response's buffer. If the client does not respond, I think the server tries sending response packets (which will get no reply) until it finally gives up after a period of time. If the user closes their browser while the page is still being processed, the server wouldn't know until it finished, and tried to start sending the response. If the user closes their browser while it is still receiving the response, I think the server would stop getting acknowledgments and would eventually time out and give up. In either case, the entire page (and all it's queries, etc) still get processed.

Re: Case Sensitive SQL
Well... Jason ID and SITE will always have unique values no duplicates allowed. Other than that, CLUSTER field can have duplicate values. In simple English if I phrase it, "Multiple SITEs can belong to a SINGLE CLUSTER" and that's why I need to GROUP BY cluster.

Re: Case Sensitive SQL
Okay, that makes sense, but I'm thinking that you won't be able to do the grouping at the SQL level in that case. As Jochem noted, GROUP BY can only put records together where all the grouped fields match, and the assumption is that all other columns are summarized or otherwise aggregated. In short, you still have to do something with the other columns (id, site, far_end, site_type, phase, lat, long, city, region, sites_status) if you try to group on cluster. Depending on what you need to do with the data on output, you might want to ORDER BY cluster and then do grouping on output (just a table-based listing example): #clust# #site# #far_end# #site_type# #phase# lat: #lat# long: #long# #city# #region# #site_status# ~| Want to reach the ColdFusion community with something they want?

Re: Case Sensitive SQL
>>ID and SITE will always have unique values no duplicates allowed. Ok, but you still have to list all columns in your SELECT list, it is a matter of SQL syntax, not logic. In pure logic, a "GROUP" clause should be enough, since one has no choice, but this is the way SQL has been designed. ~| Want to reach the ColdFusion community with something they want?

RE: User Authentication without Session Expiration
Thank you both for the assistance. I was trying to stay away from session variables, but I think I will just increase the session timeout to a couple of hours and not worry about the method I was wanting to implement. We won't have so many users that it would put a strain on our web server. Thanks, Mike -Original Message- From: Arsalan Tariq Keen [mailto:arsalk...@hotmail.com] Sent: Saturday, June 13, 2009 8:47 AM To: cf-talk Subject: Re: User Authentication without Session Expiration I suggest, you keep the credentials encrypted or decrypted as you wish, but keep them on the Application server in the session scope and for the browser thingeee use a simple cookie to maintain the heartbeat. You can use a cookie by the name 'logedin' and set its value true. Every time a new page is requested check for the session scope and the browser cookie to have the mentioned value. If the session scope expires then the user will have to sign-in again. However, if the cookie expires, lets say bcoz of closing the browser window on the client side, you can redirect the user to the signin page where its username is already being displayed and you ask for password AGAIN to continue.

Well, yet another legendary Access database bashing :-( Access database are GREAT for any small/medium web application. Most databases implement the string comparison to be case insensitive by default. They also have provisions to change it either globally or locally, and COLLATE is just one of them, not the simplest one.

Cfthread bug with sandboxing
On our CF8.01 servers we've noticed a bug with cfthread and sandboxing. Threads don't get the same permissions as the code that launched them; any action like a DB call, a file read etc taken inside a thread fails with sandbox related errors. The exception to this is the first page to call threads after a server restart; those threads get the right permissions and everything works. After this, when pages in other sandboxes try to run threads, problems occur for those other sandboxes (the first one continues to work). It's essentially first come first served, which is why I think it's a bug and not a feature. Has anyone else seen this problem? We're on SLES 10, CF Enterprise Multiserver (i.e. JRun). mxAjax / CFAjax docs and other useful articles: http://www.bifrost.com.au/blog/ ~| Want to reach the ColdFusion community with something they want?
