Does IntraWeb provide for a way to add/change browser request headers on a redirect? - I know that it's a security issue and was not traditionally possible, but apparently some such things can now be done with service workers. If there's already some plumbing for this in IW, then it would save me a lot of time. Would also be nice to know the rules: what can and cannot be done in what cases.

There are many examples of the reverse, but none that gives you ability to call a JS function on a page from Pascal. Is it possible?

For instance, I want to submit a form. Which I have just dynamically created on the page.

I know that if I add some OnLoad JS somewhere and click some button synchronously, it would re-render the form, execute that OnLoad function and this can submit my form, but I'm trying to avoid reloading the form, I want the buttons to work asynchronously, so there will be no reload and any OnLoad events there would not fire.

Without a lot of doco, everything becomes a problem. If these questions are already covered anywhere, can someone please point me there? -

1) I can see a new session created on every new request to a content handler, but at the same time, no cookie is being set. I would have thought the IW cookie should be set automatically to match the Session, so if a content handler is called 1,000 times, it would not leave 1,000 sessions behind. I'm creating content handlers with:
          CanStartSession := True;
          RequiresSessionStart := False;

Are there any tricks to it, or would session handling need to be coded from scratch, if needed? Because without this, what good are these ephemeral sessions anyway?

2) Also. can a handler be defined for a wildcard path, like /do/*? - to respond on both /do/this and /do/that?

Or defined for /do, so that requests for /do/something trigger it? - because from what I see, it's not happening.

Or can content handlers be released and recreated at runtime, i.e.: in a form event? - because I need to listen on a number of configurable paths, which may change from time to time and I would not want to restart the service every time this list changes.

3) There're AddRootHandler & AddStartHandler methods there as well. What do they do / what are they for?

I have a frame which I am displaying on four pages of a TIWTabControl. The four TIWTabPage pages are created dynamically, and as each one is created an instance of the frame is created and assigned to the page by setting its parent. There are some components such as TIWButtons on the frame and everything up to this point works perfectly.

I need to add a TIWGrid to the frame. I can place one on the frame in design time and it works but I can only update the grid on the first tab page. I figured out that this was because each instance of the grid must have a unique name. I tried setting the name in the IWFrameRegion create event but that did not work. It resulted in access violations.

So I then decided to create the grid dynamically, again in the IWFrameRegionCreate, and assign a unique name to each grid. This was partially successful.

Is this something that is currently supported, downloaded the latest source after coming across AV's with this SASL processing and it looks like this is not enabled?

Hi, 

how can I customize the application time-out message? This message appears when the user uses an expired link and the server has been restartet.

WebApplication->GotoURL() does not work at this point because there is no WebApplication (== NULL).

Does anyone have an idea?


Greetings wieczy

The new install of IW16 has blown away all the TMSiwPro components. TMS doesn't support them anymore, but they're still very good. Has anyone else encountered this and (hopefully) have a work-around?

Hi guys,

It's real!!!

IntraWeb now supports Lazarus IDE and Free Pascal Compiler. A single code base, the same solid product, the same features, now available in Lazarus. 

We have a new major version available for immediate download:

https://www.atozed.com/2024/11/intraweb-16-0-0/

Regarding Lazarus support:

- The same installer should be used for all supported IDEs (From RAD Studio 2009 to RAD Studio 12.2 and Lazarus 3.4 or 3.6)
- The same license can be used in any IDE, concurrently. You can use your active IW 15 license with IW 16 in Lazarus.
- All 4 application types are also available for Lazarus: Http.sys, ISAPI, SA-Indy, ASPX. 
- IntraWeb for Lazarus must be installed on Lazarus for Windows, 64 bits
- Versions 3.4 (from FpcDeluxe) and 3.6 (Official) are both supported
- Free Pascal Compiler 3.2.2 is supported, x64 (x86_64-win64 target only)
- Linux targets are not supported ATM. It's in our roadmap and being developed.
- Please check our site for instructions/notes on how to install IntraWeb on Lazarus/FPC: https://www.atozed.com/intraweb/how-to-i...n-lazarus/

Enjoy!  

Is there a list of what type of HTML tags can be used with all the different types of IW controls? I.e.: what goes with what?

I'm trying to use a Bootstrap template with things like:

                      <div class="card">
                        <div class="card-body">
                          <div class="card-title d-flex align-items-start justify-content-between">
                            <div class="avatar flex-shrink-0">
                              <img
                                src="assets/img/user.png"
                                alt="Users"
                                class="rounded"
                              />
                            </div>
                            <div class="dropdown">
                              <button
                                class="btn p-0"
                                type="button"
                                id="cardOpt3"
                                data-bs-toggle="dropdown"
                                aria-haspopup="true"
                                aria-expanded="false"
                              >
                                <i class="bx bx-dots-vertical-rounded"></i>
                              </button>
                              <div class="dropdown-menu dropdown-menu-end" aria-labelledby="cardOpt3">
                                <a class="dropdown-item" href="javascript:void(0);">List</a>
                                <a class="dropdown-item" href="javascript:void(0);">Manage</a>
                              </div>
                            </div>
                          </div>
                          <span class="fw-semibold d-block mb-1">Users:</span>
                          {%lblUserCount class="card-title mb-2"%}
                        </div>
                      </div>


I want the image to be static, as it is. But ideally clickable. Do I have to replace the entire IMG with an IW component? Or wrap it into an <A></A> (and then if I do, how do I link that to an IW button, for example)?

And with classes/styles in the HTML, how can I link a button (or anything) back to <A>? And then can I push styles/classes back to HTML controls (whether I do or do not map them to anything from code)? Like the "active" below, when the next item is clicked:

[...]
          <ul class="menu-inner py-1">
            <li class="menu-item active">
              <a href="index.html" class="menu-link">
                <i class="menu-icon tf-icons bx bx-home-circle"></i>
                <div data-i18n="Analytics">Dashboard</div>
              </a>
            </li>

            <li class="menu-item">
              <a href="javascript:void(0);" class="menu-link menu-toggle">
                <i class="menu-icon tf-icons bx bx-layout"></i>
                <div data-i18n="Layouts">Layouts</div>
              </a>
[...]


Or does the entire structure need to be replaced with a Tab control for this?

It really needs another Guide, it's a whole new field...

My Client is failing to logon to my server now and I think this is an upgrade woe (I'm using 10.6.3.3)

The client sends a string command like this: logon¦<username>¦password

After being stumped as to it not working anymore, I ended up doing a debug and seeing that the clients TCP thread is sending it but the server isn't happy - and sends back a 400 quoting it with ? instead of ¦

So I went and debugged the server and the TIdCmdTCPServer.DoExecute function is reading it in as: logon?<username>?password

Clearly this is not what was sent however ¦ is turning into ?

In IdGlobal there is this function that the client calls when calling WriteLn():
