Enjoy! 

Good afternoon! I recently bought a license for Ultimate. Please explain how to get the documents confirming the purchase? My accounting department requires a document that confirms that the purchase has been made.

I apologize that I have to write this question on the forum, but there is no answer to my appeal to the personal account. 

I need some kind of document that would confirm that my money was spent on the purchase of the Ultimate Intraweb license.

I am using IW 14.2.9 ultimate with Delphi 10 Seattle 
Installed components : TMS and CGDevTools
External connection is done thru an proxy server.

I encounter a strange situation, service is running ok several days, but are moments when become unresponsive.
Server processor goes above 25 % and everything respond in 10-20 sec or even get timeouts.

Restarting service do not solve the problem, because instantly server get back to 25-30 %. Memory consumption is not height and third server (database layer) is working ok for other clients as well.

I did also a new installation of  IW service on second server and from proxy I activate which server to run. But when are problems, Proc constantly > 25 % switching servers do not solve anything. Second server goes instant to the same proc usage and also become unresponsive.
That takes  from 5 min to 40 min, till everything goes back to normal and server respond in milliseconds.

What I didn't understand, is , when busy, why do not show at list page of login (that is simple and do not connect to any third party service) when start.
Why server does instantly at 25-30 % when restarting ?!
In logs are nothing strange, no exceptions reported.

Please, any suggestion is very welcome.

config:
  self.RestartExpiredSession := True;
  Self.BoundIP := FConfig.CFG.ReadString('Server','BoundIP',False);
  self.Port := FConfig.CFG.ReadInteger('Server','BoundPort',False);
  self.AllowMultipleSessionsPerUser := false;


 Self.SessionTimeout := 120; {2 hours}
 Self.FilesDir :=  Self.ContentPath + FConfig.CFG.ReadString('Server','SharedFilesDir',False);
 Self.InternalFilesDir := Self.ContentPath + FConfig.CFG.ReadString('Server','SharedFilesDir',False);


TIWSecurityOptionsAccess(Self.SecurityOptions).mCheckSameIP := False;
TIWSecurityOptionsAccess(Self.SecurityOptions).mCheckSameUA := true;
TIWSecurityOptionsAccess(Self.SecurityOptions).CheckFormId := true;
SecurityOptions.ShowSecurityErrorDetails := False;

CookieOptions.SessionCookies := false;
CookieOptions.HttpOnly := true;
CookieOptions.UseCookies := True;

  self.JavaScriptOptions.AjaxErrorMode := emNone;
  self.LogCommandEnabled := true;
  self.LogSessionEvents := true;

  self.ExceptionLogger.RegisterIgnoreException(EConvertError);
  self.ExceptionLogger.RegisterIgnoreException(EUnknownBrowserException); {Unknown browser type}
  self.ExceptionLogger.RegisterIgnoreException(EInvalidSession); {Invalid session}
  self.ExceptionLogger.RegisterIgnoreException(EExpiredSession); {Expired session}
  self.ExceptionLogger.RegisterIgnoreException(EIWNoSessionId); {No session ID}

  self.ExceptionLogger.LogType := ltFile; // ltEventLog;
  self.ExceptionLogger.FilePath := Self.ContentPath + 'Exceptions\';
  self.ExceptionLogger.FileName := 'Exceptions.log';
  self.ExceptionLogger.PurgeAfterDays := 1;
  self.ExceptionLogger.Enabled := True;

Where can I find a description of all the parameters of the ShowPrompt call ? 
Interested in the format of specifying the last parameter (callbackData: TStrings)

In which directory should the IntraWeb sources be placed so that they are available in DesignTime In Delphi XE7

Hi guys,


there is a new update available, IW 15.2.35:

https://www.atozed.com/2021/08/intraweb-15-2-35/

This update is a *must* have for developers using IWjQGrid and IWBoostrap. Also, other important bug fixes (fixes a Http.sys memory leak introduced in previous version).

Enjoy! 

Hi Alexandre,

I have 2 servers with URL registration, which are now displayed differently in the address bar of the browser:

https://Mydomain.com/URLBase1/
https://Mydomain.com/URLBase2

One URL has a slash at the end now, the other doesn't.
I think that has changed in version IW15.2.33.

I also installed a new catch-all content handler.

Unfortunately, the catch-all content handler now triggers immediately for the second URL without a slash at the end.

I recently upgraded our member portal by connecting it to an identity server through crosstalk.   Since we have pushed it out it will run about 2 hours and then it spike to 100% when it gets under a heavy load.   Any ideas?  We are using IWRtlFix so I know that is not the issue.

iw 15.2.25
Is it deployed under IIS.

We've been using Intraweb 14.1.13 for quite a while (I'm currently updating to 15), and we've run into some sort of hard limit on our AWS windows server on how many intraweb stand alone services we can run at the same time. Our customers are insurance agencies. We run a web application for them as a stand alone Intraweb service for each of our agencies. We run these on Amazon AWS windows server 2012 r2 ec2 instances. Each service connects to it's own database on an MS SQL 2014 community instance on the same server. Right now, memory is only at 57%, CPU never gets higher than 20%, plenty of empty diskspace. I can run 68 Intraweb services at once. When I add a new service for a new customer and try to start it, I get "Error 1053: The service did not respond to the start of control request in a timely fashion.". If I stop a currently running service, then I can start the new one. I created two Intraweb 'Hello World' services, one with version 14, and one with our new 15 version using Http.sys. I get the same result with those. With 68 services running, I can't start the Hello World service unless I stop a currently running service. However, I can start any other NON intraweb service. I have created a number of .Net services for various purposes on those servers and can start any number of them without problems.  

Does anyone else deploy their applications in this manner? (individual stand alone service per customer) Has anyone else run into this? The server has the resources to handle running quite a few more services. We have several AWS instances in different regions and I've run into this on three different servers.

I'd appreciate any thoughts anyone has on this crazy problem. Maybe I'm crazy, I'm not sure.

Thanks!

I use chartjs.org in my HTML template with variables

<script>
var cType="bar";
var xValues=["Item1","Item2","Item3"];
var yValues=[34,12,45];
....

</script>

I will with IWButton click change this variables and draw chart?

I tried with WebApplication.CallBackResponse.AddJavaScriptToExecuteAsCDATA('var cType = "line";'); and not work!

Maybe is any variant this implementation with RegisterCallBack for change my variables?
