Hi,

this seems to be a big one related to our old friend IE.

I read a lot of googled pages and it seems to be true:
The IE does NOT display .png images when using a secured SSL (https) connection!

Can anybody confirm that?

What the hell can I do now? I want to present my new RAP demo app to some potential customers soon and they wanna see SSL Embarrassed

I never expected to get such fxxx problems.

So if anybody out there has an idea, I really appreciate this.

Thanks in advance,
Ingo

This is news to me too. Can you give a link or two that explain the
problem in detail? I can't imagine that there's no workaround. I can
open https://www.google.com/ (which has .png), and it looks fine.

What PNGs are the problem exactly? From the theming (icons, etc), or
only from your application (used on Labels, Items, Backgrounds, etc.)?

Greetings,
Tim

Hi Ingo,
just tested our Controls Demo over SSL and all images are in place (RAP
from Git master). I'm hearing for such a problem for the first time.
Could you try our Controls Demo as well?
Best,
Ivan

Hi,

the problem are for all pngs, so own and theming ones.
I stopped searching for my error, as I found a lot of result when googling for "ie png ssl" stating its a known problem.
Especially this one: http://idea15.wordpress.com/2009/06/17/fixing-the-png-bug-in-ie7/
Eventhough I'm using IE9 the problem seems to be related to Quicktime. I tested on several pcs with and without QT and the pngs shows on all w/o QT. Thats funny Evil or Very Mad
I will make further tests now...

Hi,

I have to come back to this topic as it is a big blocker for our project.
We have now successfully running our server with a GlobalSign SSL certificate.

I started the RAP demo directly from Eclipse running on the server. The problem occures together with the business or fancy design, so I used the workbench demo.
I'm using RAP 1.5.0.20120612 and the following params:
-Dorg.eclipse.equinox.http.jetty.https.enabled=true
-Dorg.eclipse.equinox.http.jetty.https.port=443
-Dorg.eclipse.equinox.http.jetty.ssl.keystore=C:/Server/www.xxx.com.jks
-Dorg.eclipse.equinox.http.jetty.ssl.keypassword=xxx
-Dorg.eclipse.equinox.http.jetty.ssl.password=xxx


On Firefox/Chrome/Safari everthing works with http and https, on IE7,8,9 it works just with https, but with https it is quite ugly. See attached screenshots.

Here with http on IE9 everything is good:
index.php/fa/11598/0/

Here with https on IE9:
index.php/fa/11597/0/

I have no idea what to do now, so any help is really appreciated.

Thanks in advance,
~Ingo

Hi.

> I have no idea what to do now, so any help is really appreciated.

Let's try this:
* Open IE
* Press F12 to bring up the debug-console
* Switch to the "Network" tab
* Click "start recording"
* Start the RAP application, wait for it to load completely
* Click "stop recording"
* Make screenshots of the resulting table and of the various tabs in the
detail view of one of the failed requests for an image.

Perhaps we can lern something from this.

Greetings,
Tim

I found out that it always works in the local browsers of my servers (HostEurope Virtual Server L and Amazon EC2 Maschine) and not on connections over the Internet. The F12 console in IE shows "Abgebrochen" which means "Aborted" for the relevant images. So I guess it is kind of a timeout.
The IE is not waiting long enough. I did not found any timeout settings I can tweak. Also we are talking about something under 1ms, which is not what a timeout covers typically.

I attached the main view of the Network tab when connection to the login view of our own app. The gray RAP background and an icon are missing and you see exactly 2 aborted image requests. The detailed tab are completly empty for that two, so I didn't attached them.

This is a really weird problem for me and again any help is highly appreciated.

Hi Ingo,
once again... just tested Controls Demo over SSL in IE9 (Windows 7 with
QuickTime installed) and all images are in place. I didn't test it over
Internet.
I really have no idea what could be the problem.
Best,
Ivan

Hi Ivan,

could you please test the workbench demo with the layout design demo "business" or "fancy"?

I was not clear at this point, sorry for that, but for me the error comes when using the designs. The control demo is ok for me too.
I forgot to mention that, sorry.

It would be very interesting to know if you have the error then also.

Thanks,
~Ingo

Hi.

> Nobody an idea?
> Do you need more information?

The big problem is that we are unable to reproduce it. Your screenshot
gives us some infos, but i can't really derive any clues from it where
to look for the problem. Perhaps you can give some more info:

* What RAP version are you running exactly?
* Could you try applying the patch attached to this bug:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=362921
For that you need to import the org.eclipse.rap.rwt bundle and use it
in your launch config.
* Did you try another certificate? Just to see if it's related to the issue.
* You mentioned it might be related to Quicktime. Does this still hold
true? Does it always work if no Quicktime is installed?
* You mentioned that all IE (7-9) have that issue. Is there anything in
common with these IE installations? What windows versions are they
running on? (Might help to reproduce it.)
* Do the failed requests always look like in your screenshot? (Multiple
tries for the same image, <img> as initiator?)

Greetings,
Tim

Another idea: Could you check your security settings for IE?
By default they are set to "middle" ("Mittelhoch") for "internet" zone
and "low" for "intranet" zone. Is this the case? What happens if you
change them all to "middle" or all to "low"?

I tried a lot of different things to track down the problem:

  • I added the site to the trusted sites
  • I removed ALL security settings from IE that can be "clicked"
  • I tried 3 different certificates (The one from GlobalSign and two own ones)

Here comes the facts:

  1. The quicktime topic is not true anymore, this was a wrong direction
  2. The IE are from different of our test customers, from simple installation (mostly Win7 & IE9) to bigger Citrix installations (IE8 & 9, Win7)
  3. We are using RAP version 1.5.0.20120612-1458.
  4. The screenshots look always like the one I posted earlier.


But now it comes: This bug SOLVED the issue: https://bugs.eclipse.org/bugs/show_bug.cgi?id=362921

In the bug Cole Markham could not reproduce the problem, I can. It is only if you use https. The solution is to always add extensions to the generated files, thats all.
I hope that this could be integrated soon.

Thank you all for your help,

~Ingo

Ingo,

Yes, I'm still around.

I'm glad the patch worked for you. I knew your problem sounded familiar, but I had forgotten about this patch and that it hasn't been added to RAP yet. In our case, it failed consistently at one of our clients, but we could never reproduce it locally. We were also using SSL (using Apache as a reverse proxy).

I will try to get some unit tests written and get this committed.

Cole
