Yes, SSL pinning is a possibility. Although as of iOS 10.3, you must take an additional step to trust the Charles Root Certificate &lt;s&gt;that is not currently documented on their website&lt;/s&gt; &lt;b&gt;edit: this info is now under iOS Devices here: https://www.charlesproxy.com/documentation/using-charles/ssl-certificates/&lt;/b&gt;

    Settings &gt; General &gt; About &gt; Certificate Trust Testings

Source: https://www.neglectedpotential.com/2017/04/trusting-custom-root-certificates-on-ios-10-3/

There are applications which don&#39;t simply expect the certificate signed one of the trusted CA&#39;s on the system, but which expect a single specific certificate or a certificate containing a specific public key. This is called certificate/public key pinning. For this application it will not work if you configure the CA of Charles Proxy as trusted on the system because they will not use this CA. 

&gt; Any explanation of this/way to fix it?

If the application is built to only trust a single certificate/public key and never trust something just because it is signed by a locally trusted CA, then you would need the original certificate and its private key to do the SSL interception. Since you don&#39;t have these there is no way to do the SSL interception.

I am using Charles Proxy to see all of the traffic that is coming out of my iphone. I have the ssl certificate/profile installed on my iphone and I can see a lot of the traffic that is ssl encrypted. However, some applications seem to not finish the ssl handshake. 

The error is: &quot;SSLHandshake: Remote host closed connection during handshake&quot; and then Charles Proxy suggests to configure the application to trust the Charles Root Certificate. I thought I did when I installed the profile onto my iphone?

I have a `UICollectionView` with a `segmented control` to switch between data. But how do I change the `UICollectionViewCell` size properties **programmatically** ? then I can custom each style appropriately for each data type. 

**For example** change the width to 520 points and height to 100. I am new to iOS development and am experienced with CSS :/

I know how to do it in Xcode (obviously) but do not know the correct methods to change it in swift. Any ideas or feedback is much appreciated (Y)

I am writing a server for an iOS game. The game is turn-based and the only time the server needs to push information to the client is to notify of the opponent&#39;s move.

I am curious if anyone could comment on the performance and ease of implementation differences between using WebSockets and long polling. Also, if I used WebSockets, should I only use it to receive information and send POST requests for everything else, or should all communication be through the WebSocket?

Additionally, is there anything extra to consider between WebSockets and long polling if I am interested in also making a web client?

I imported an Obj-C file into my swift project and Xcode automatically prompted me to create a bridging header file as expected. However, I deleted both the files (moved to trash) to make some changes, but when i try to import the Obj-C file once again, the prompt doesn&#39;t come up anymore. What is the reason? I even tested this same scenario in another project, It seems once I delete Xcode&#39;s auto created bridging header, It won&#39;t bring the prompt up again another time. Why is this?

I&#39;ve got a JavaScript web app working that plays some audio periodically like this:

    var SOUND_SUCCESS = new Audio(&#39;success.mp3&#39;);
    SOUND_SUCCESS.play();

This works great on desktop browsers (tested in Edge and Chrome), but it doesn&#39;t play on Safari on iPhone.

I&#39;ve looked around Stack Overflow, and I found some answers from a couple of years ago that it&#39;s not possible to play audio from Safari unless you&#39;re in that full screen player. Is this still the case?

Why can&#39;t JavaScript .play() audio files on iPhone safari?

I&#39;m working on a project where I have two `UITableView`s and two `UITextField`s, when the user presses the button the data in the first `textField` should go into the `tableView` and the second go into the second `tableView`. My problem is that I don&#39;t know how to put data in the `tableView` each time the user pushes the button, I know how to insert data with `tableView:cellForRowAtIndexPath:` but that works for one time as far as I know. So what method can I use to update the `tableView` each time the user hits the button?

So, I was having an issue earlier today where my client, written in `node`, was barfing because the server I was connecting to used self signed certs. So, I went and added the option `rejectUnauthorized: false` to my `tls.connect` command like any unwitting developer would do.

My question is now, what the hell does this mean for me? Is my TLS connection just a vanilla TCP connection that can also possibly be a TLS connection? Is writing this as a TLS stream totally useless?

More importantly, that server, you know the one with the self-signed certs? Is my stream between here and there actually encrypted?

TLS what exactly does &#39;rejectUnauthorized&#39; mean for me?

I am getting the following error when connecting to a SQL Server database using version the Microsoft JDBC Driver:

&gt; com.microsoft.sqlserver.jdbc.SQLServerException: The driver could not establish a secure connection to SQL Server by using Secure Sockets Layer (SSL) encryption. Error: &quot;SQL Server returned an incomplete response. The connection has been closed. ClientConnectionId:98d0b6f4-f3ca-4683-939e-7c0a0fca5931&quot;.

We recently upgraded our applications from Java 6 &amp; Java 7 to Java 8.  All systems running Java are running SUSE Linux Enterprise Server 11 (x86_64), VERSION = 11, PATCHLEVEL = 3.

Here are the facts I have collected with a Java program that I wrote which simply sequentially opens and closes 1,000 database connections.

 - Connections are dropped with this error about 5%-10% of the time.  The error DOES NOT occur on every connection.
 - The problem ONLY occurs with Java 8.  I ran the same program on Java 7 and the problem is not reproducible.  This is consistent with our experience in production prior to upgrading.  We&#39;ve had zero problems running under Java 7 in production.
 - The problem DOES NOT occur on all of our Linux servers running Java 8, it only occurs on some of them.  This is perplexing to me, but when I run the same test program on the same version of the Linux JVM (1.8.0_60, 64 bit) on different Linux instances, the problem does not occur on one of the Linux instances, but the problem does occur on others.  The Linux instances are running the same version of SUSE and they are at the same patch level.
 - The problem occurs when connecting to BOTH SQL Server 2008 and SQL Server 2014 servers/databases.
 - The problem occurs regardless if I am using the 4.0 version of the SQL Server JDBC driver or the newer 4.1 version of the driver.

The thing that makes my observations unique on this compared to others on the web is that although the problem happens ONLY on Java 8, I cannot get the problem to occur on one of the seemingly identical Linux servers that is running the same Java 8 JVM.  Other folks have seen this problem on earlier versions of Java as well, but that has not been our experience.

Any input, suggestions, or observations you may have are appreciated.

I am developing a Java application that queries a REST API on a remote server over HTTP. For security reasons this communication should be switched to HTTPS.

Now that [Let&#39;s Encrypt](https://letsencrypt.org/) started their public beta, I&#39;d like to know if Java currently works (or is confirmed to be working in the future) with their certificates by default.

Let&#39;s Encrypt got their intermediate [cross-signed by IdenTrust](https://letsencrypt.org/certificates/#cross-signing), which should be good news. However, I cannot find any of these two in the output of this command:

    keytool -keystore &quot;..\lib\security\cacerts&quot; -storepass changeit -list

I know that trusted CAs can be added manually on each machine, but since my application should be free to download and executable without any further configuration, I am looking for solutions that work &quot;out of the box&quot;. Do you have good news for me?

Does Java support Let&#39;s Encrypt certificates?

https://github.com/angular/angular-cli#proxy-to-backend here is an instruction how to do proxying to backend. I did everything step by step and still requests aren&#39;t proxied.

8080 - my Express backend
4200 - my Angular2 frontend

In Angular2 project I have file ```proxy.conf.json``` with content like this:

    {
      &quot;/api&quot;: {
        &quot;target&quot;: &quot;http://localhost:8080&quot;,
        &quot;secure&quot;: false
      }
    }

In Angular2 package.json I changed ```start``` procedure to ```&quot;start&quot;: &quot;ng serve --proxy-config proxy.conf.json&quot;```

When I type inside commander ```npm start``` then at the start I can see ```Proxy created: /api -&gt; http://localhost:8080```. Well, so far is good I guess.

I&#39;m trying to send a request (Angular2)

      constructor(private http: Http) {
        this.getAnswer();
      }
    
      getAnswer(): any {
        return this.http.get(&quot;/api/hello&quot;)
          .subscribe(response =&gt; {
            console.log(response);
          })
      }

I&#39;m getting an error that ```http://localhost:4200/api/hello 404 (Not Found)```. As we can see, nothing has been proxied. Why? Did I do something wrong?

To be clear. When I go manually to ```http://localhost:8080/hello```, all works fine. There is nothing to look for in backend side.

Angular-CLI proxy to backend doesn&#39;t work

I have this code in js bin: 



    var validator = {
      set (target, key, value) {
        console.log(target);
        console.log(key);
        console.log(value);
        if(isObject(target[key])){
          
        }
        return true
      }
    }
    
    
    var person = {
          firstName: &quot;alfred&quot;,
          lastName: &quot;john&quot;,
          inner: {
            salary: 8250,
            Proffesion: &quot;.NET Developer&quot;
          }
    }
    var proxy = new Proxy(person, validator)
    proxy.inner.salary = &#39;foo&#39;




if i do `proxy.inner.salary = 555;` it does not work.

However if i do `proxy.firstName = &quot;Anne&quot;`, then it works great.

I do not understand why it does not work Recursively.

How to use javascript proxy for nested objects

I&#180;m performing some WPO tasks, so PageSpeed suggested me to leverage browser caching. I have improved it successfully for some static files in my Nginx server, however my image files stored in Amazon S3 server are still missing. 

I have read an approach regarding update each file in S3 to include some header metatags (Expires and Cache-Control). I think this is not a good approach. I have thousands of files, so this is not feasible for me.

I think a most convenient approach is to configure my Nginx 1.6.0 server to proxy the S3 files. I have read about this, but I&#180;m not skilled at all on server config, so I got a couple examples from these sites: https://gist.github.com/benjaminbarbe/1961db5ffbaad57eff12 


I added this location code inside my server block in my nginx config file:

    #inside server block
    location /mybucket.s3.amazonaws.com/ {
		    		    
		 
		    proxy_http_version     1.1;
		    proxy_set_header       Host mybucket.s3.amazonaws.com;
		    proxy_set_header       Authorization &#39;&#39;;
		    proxy_hide_header      x-amz-id-2;
		    proxy_hide_header      x-amz-request-id;
		    proxy_hide_header      Set-Cookie;
		    proxy_ignore_headers   &quot;Set-Cookie&quot;;
		    proxy_buffering        off;
		    proxy_intercept_errors on;		
		    proxy_pass             http://mybucket.s3.amazonaws.com;
		  }

For sure, this is not working for me. No header is included in my requests. So, first I think the requests are not matching the locations.

I am in a corporate env so I have to use a proxy to reach servers. This works well in postman and in browsers. What I can&#39;t reach is localhost in postman but I can reach localhost in the browser. 

I am running Postman for Linux Version 6.0.9. I have tried reaching localhost:9082/rest/myapi.... and 127.0.0.1:9082/rest/myapi with both global proxy and system proxy turned on and with either turned on and with non turned on. In all cases I am not able to reach localhost.

What I get as an response is an error page from the proxy server! Someway the call gets out on the network instead of being kept on my machine.

The postman console:

My request headers are:

    Cache-Control →no-cache
    Connection →Keep-Alive
    Content-Length →986
    Content-Type →text/html; charset=utf-8
    Pragma →no-cache
    Proxy-Connection →Keep-Alive

My response headers are:

    cache-control:&quot;no-cache&quot;
    pragma:&quot;no-cache&quot;
    content-type:&quot;text/html; charset=utf-8&quot;
    proxy-connection:&quot;Keep-Alive&quot;
    connection:&quot;Keep-Alive&quot;
    content-length:&quot;986&quot;

My response body is an html page.

How can I make a call to `localhost` work with postman?

I was snooping through my MSP430 microcontroller&#39;s header files, and I ran into this in `&lt;setjmp.h&gt;`:

    /* r3 does not have to be saved */
    typedef struct
    {
    	uint32_t __j_pc; /* return address */
    	uint32_t __j_sp; /* r1 stack pointer */
    	uint32_t __j_sr; /* r2 status register */
    	uint32_t __j_r4;
    	uint32_t __j_r5;
    	uint32_t __j_r6;
    	uint32_t __j_r7;
    	uint32_t __j_r8;
    	uint32_t __j_r9;
    	uint32_t __j_r10;
    	uint32_t __j_r11;
    } jmp_buf[1]; /* size = 20 bytes */

I understand that it declares an anonymous struct and typedef&#39;s it to `jmp_buf`, but I can&#39;t figure out what the `[1]` is for. I know it declares `jmp_buf` to be an array with one member (of this anonymous struct), but I can&#39;t imagine what it&#39;s used for. Any ideas?
