I want to perform load test of ios mobile app using Jmeter but I am facing issues in configuring my mobile phone. I have installed Jmeter and added recording template in it and set the port no of HTTP Test script recorder to 8888. I have also installed and trusted the certificate in my mobile device and set the proxy settings of my device by giving IP and port no. But after setting proxy I am unable to access the internet. Apps as well as other websites on chrome etc stops working due to loss of internet and when I remove proxy it starts working fine.
It's hard to say what is wrong without seeing jmeter.log file preferably with debug logging enabled for the proxy components, it can be done by adding the next line to log4j2.xml file (it's located in JMeter's "bin" folder)
<Logger name="org.apache.jmeter.protocol.http.proxy" level="debug" />
A "blind shot": in order to provide Internet access to the iOS device JMeter must have Internet access itself. Try adding a Thread Group and a HTTP Request sampler manually pointing to some site in the Internet which works for sure, i.e. http://example.com may be a good choice. Then add a View Results Tree listener and run the test. If the test fails it means that JMeter cannot access internet and most probably you need to configure it to use your corporate or ISP proxy
If the test is successful - look into the log files for JMeter and iOS and try to figure out the cause of the problem from them. If you fail to do this yourself - either update this thread with your configuration details and log files or ask a new question

My corporate VPN blocks all external traffic from an Android device. I am trying to test PWA that is internally hosted (all resources inside a firewall). What I observe is that despite passing Lighthouse audit my PWA fails the WebAPK creation process on a device. Specifically, the install process takes a long time, and eventually it degrades to an application shortcut install.
What I did:
Built the simplest PWA that I could think of (index.html registering service worker + sw.js with fetch even handling index.html request offline + web manifest) and hosted it on an internal server
Run Lighthouse audit on the desktop and made sure it passes all PWA Lighthouse audits
Run bubblewrap init on the manifest to double check that icons/names are OK
Tried to install PWA on an a Pixel phone from Chrome's dot dot dot menu behind firewall
After a long time, the application shortcut was installed (with Chrome overlay icon)
Checked chrome://webapks/ on my phone - no surprises here, I did not find WebAPK for my app
Turn on my corporate VPN workaround, which allows me to bypass VPN restrictions and access external addresses (rooted phone + ProxyDroid hackery)
Now WebAPK creation works
Question 1:
Could someone please explain what is involved in WebAPK creation that would make it fail behind a strict corporate firewall? Is there any external resource (a service perhaps?) involved here that I could advocate my corporate VPN to whitelist? If not, any advice of how to have automatic tests for WebAPK creation would be appreciated. I thought of using bubblewrap build, but, since it is for TWA's, I did not expected it to pass for my simple PWA.
Question 2:
In general, what is the best technique for diagnosing WebAPK creation failures for PWA's that pass Lighthouse audit?
The WebAPK is generated server-side by Chrome. Chrome sends details from the manifest, along with the icons to it's server, which then returns the WebAPK. As you pointed out, it's most likely your corporate firewall is blocking that request to the server, preventing Chrome from generating the WebAPK.
The code for generating WebAPKs in Chrome can be found here
For your second question, we don't really have good tools for debugging that, if Lighthouse passes, it should build the WebAPK (with the exception noted above). I suspect you could connect the device to your computer and use ADB to look at logs, but thats... ugly. Sorry.
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 need to show to a user an interface of some application running on a server using a browser. It should be like RDP-client for a single application on a server.
Are there any solutions or services that can implement following functionality? Maybe Citrix?
Thanks in advance!

About FreeRDP-WebConnect
FreeRDP-WebConnect is an open source gateway for accessing RDP
sessions using any HTML5 compliant browser. In particular it relies on
the Canvas and the WebSockets feature. FreeRDP-WebConnect is a
subproject of the FreeRDP project.
On the server side, a standalone daemon - written in C++ - provides a
Web page via HTTPS (or HTTP, if configured) and uses FreeRDP libs to
connect as a client to any RDP session. The server side WebSockets
implementation handles current RFC6455 only, so browsers that
implement the older drafts do not work. With RFC6455 being raised to
the "Proposed Standard" level, this should change now really soon.
I would create an account on the server for the user, and only give it access to the one application it needs access to.
You can use Cameyo. To start, create yourself a free account, and click on "Add App". If your installer supports unattended installation, you simply need to submit it. Otherwise, you can build a Cameyo package locally and send it in. It will then be playable as HTML5.
You don't indicate what server you are running on.
As an alternative to FreeRDP-Webconnect cited above, also open source and also using FreeRDP as rdp client through an HTTP gateway, there is Myrtille.
FreeRDP-WebConnect embeds a standalone daemon written in C++ to provide a web page via HTTP(S), and so will also work on Linux servers, while Myrtille have a IIS/.NET (C#) implementation and an MSI installer, thus is more intended for Windows Servers.
I know this has some crossover to Serverfault.com but the advice on meta.stackoverflow was to ask it here (first) as it requires a .NET dev to answer more than likely.
I am having some problems publishing to my website a Click Once App, I am getting an error message saying (something like) IIS not running, I'm not currently at home to give an exact error message, i'll edit later if it is required to answer this question.
My ISP is lunarpages the plan I am on is this one IIS is definitely running as I have BlogEngine.NET running just fine. Anyone know what is required configuration wise (both server and client) to make this work?
The files that the ClickOnce publish create can be run on just about any web environment (include Apache/Linux.) It simply generates an html page along with the application manifest and your application files. Maybe you can deploy to a local folder and upload the files to the server?
