I have a Facebook canvas app that calls various external files over https. When loading FB over http and then navigating to the app, I get the message "Internet Explorer blocked this website from displaying content with security certificate errors."
I realize there could be any number of culprits in a mixed environment, but how to best troubleshoot the specific request(s) that trigger the error? The IE dev tools don't provide a clue, as the error is not reported in the network or console tab. When I view the same page in Chrome, I get no SSL error, so I can't find a clue there.
Essentially what I've done so far is to proceed by clicking "show content", logging all the https requests in Charles, then trying them all individually in IE to see if any trigger the error out of context.
thanks
The F12 Tools Console typically will show the exact source of a HTTPS error, as will the Fiddler Web Debugger. Is there a repro URL we could look at?
Do you have fiddler or httpwatch to figure out whether the request is being forwarded to another secured (https) URL?

I am developing a web-app which will manage user page posts etc,
My app in Facebook developer console is in development mode, but when i try to login in http://localhost then it gives error that facebook login does not allow http but i have to use https protocol.
Any solution to test facebook login in localhost with http ? or
Any idea to convert http to https in localhost?
I tried ngrok that converted http to https but facebook developer console said it is suspicious kinda link and refused to accept;
I am using a npm pakage react-facebook-login,
I will shift to pure code of facebook sdk if that will solve problem.
This is a solution I found for create-react-app. https://create-react-app.dev/docs/using-https-in-development/
Make sure you use the right terminal and it works. For instance, I started dev in the cmd line (set HTTPS=true&&npm start).
The downside is you still will get not secure warnings in the browser but the errors with the FB.login or similar from Facebook login packages went away. Hope it helps.
In FireFox I load my web application which has a Source Map. The Source Map seems to be loaded correctly, as the Debugger tab shows the original source files.
However, the Console tab contains only links to the compiled code, instead of the Source Map code.
Is a Source mapping done in FireFox Console?
Do I have to enable anything?
Update: I also tried it in chrome and there the console shows the original location of the event, BUT: only the first time after starting chrome AND only, if I first load the page and then open the developer tools. Exactly same behaviour in opera (same engine...)
Update 2:
As of Firefox bug 670002 Web console does still not support source mapping.
In chrome the source mapping works more than once if I directly embed the source mapping instead of using an URL.
For chrome developer tools, the answer was covered in this issue:
https://bugs.chromium.org/p/chromium/issues/detail?id=633549
In some cases, developer tools requested the source map file when no connection was alive anymore. It tried to open a new connection, which failed silently because of an invalid ssl certificate.
You may run into this, when:
You serve using https
You do not have a valid ssl certificate (which may happen often when you just run a quick local node.js https server)
Your https server closes the connection fast or immediately
Especially when your https server sends connection:close in the response headers you may run into this.
The biggest issue is, that this request is not shown in the network tap nor in the console, it is just silent.
I am developing a Telco application (Dyanamic Web application project to send and receive sms) using Eclipse & tomcate version 7
When I try to run it on
http://localhost:8080/SMS1
It gives an error message HTTP-ERROR-CODE:302
What should I do to resolve this error
This is the link to Application and video tutorial what I am following
https://drive.google.com/file/d/0B3VmCeqDC7SDcFZaWVZhRUNmaTQ/edit?usp=sharing
HTTP code 302 is a standard "redirect" message--that is, it tells your web browser that the page was moved and where the new page can be found. I'm guessing whatever you're using as a web browser (Eclipse?) just doesn't handle that type of redirect. Try using a standard web browser like Chrome or Mozilla to see if that helps...
Also a guess, but the redirect may be trying to move you to HTTPS instead of HTTP, and your certificates may not be set up properly, or the port isn't enabled, or there may be some other problem with your HTTPS configuration. If the app is supposed to work over HTTPS, try going directly to the HTTPS version of the link to see if that's the real issue.
A third guess is the app may be trying to redirect you to a login page if you're not logged in, and maybe it can't find it. I'd need to know a lot more about the built product and I really don't want to mess with some guy's shared Eclipse project. Tell them to use a build tool!
I am using the Facebook JavaScript SDK for a project I'm currently working on. It's been working fine before, but when I opened it today, the URL http://connect.facebook.net/en_US/all.js is not accessible. When I inspected the network using Firebug, I noticed that the server was returning 403 Access Denied.
Is there something I am getting wrong or is it Facebook server problem?
Finally figured out that Facebook's new HTTPS feature is interfering. Using https://connect.facebook.net/en_US/all.js solves the problem. Seems someone misconfigured their servers.
I'm trying to automate access to a website that get reports from a Microsoft-IIS/6.0 server, or at least I assume that because that is what is appearing in the HTTP Headers. So if the website connects this server, does it download the file via FTP? Is there any way that I can find out the commands being sent form my browser?
The weird thing about the website is that it uses Crystal Report ActiveX viewer, is that client side, is there any way that I can control the viewer through PERL?
Also, this might be a really dumb question, but does IIS use SQL/MySQL?
Any help is appreciated!
There are a lot of ways to watch the traffic being sent between your browser and the server.

Chrome has it built in by hitting ctrl+shift+i
