I need to identify and restrict calls to the server (web service) if server certificate is revoked. I am able to restrict the service call if certificate is “invalid", but if the certificate is “revoked” the restriction is not working.  Case 1: (Working) URL: https://www.drobnik.com/ For this URL, certificate is “untrusted” (firefox Error code: ssl_error_bad_cert_domain). In this case, restriction from NSURLConnection is working fine, i.e. request is getting terminated. For untrusted certificate i.e. www.drobnik.com, NSURLConnectionDelegate method - (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)pError gets called. The error object is as below. Error Domain=NSURLErrorDomain Code=-1202 "The certificate for this server is invalid. Case 2: (Not Working) URL: https://revoked.grc.com/ For this URL, certificate is “revoked” (firefox Error code: sec_error_revoked_certificate).

Maintainability – In future they will need two skill set people with classic ASP and .NET. Code base – As a part of maintainability also as the .NET code  base is lesser in size typically Performance - Classic ASP is using Inline Queries. We are planning to use entity framework and that performance is good. Outdated technology- No object orientation concepts in ASP and .NET code is more structured and modular Security- SQL injection has been implemented in current codebase using ASP but you are never sure. Newer frameworks are always more secure. Browser Support - Browser support is limited in ASP. Browser compatibility has to be sorted out with many workarounds. Faster Development time – Future enhancements will be faster as in ASP you have to build a lot of functionality yourself, where as in .NET has in build feature

Thanks to a conversation with Pavan here it is….   Debugging is a hassle Visual Layout is good in ADF ADF you need to deploy and you can see so time takes to do. Web UI in ADF compared to Titanium Many UI components in ADF compared to Titanium e.g carousel If you make a mobile ADF you are all set for ADF Web and Web Service so skills are transferrable Good tools to connect with Database using pre-defined libraries in ADF compared to ADF Landscape and Portrait is difficult to ADF Accommodating Different Screen sizes is difficult in ADF ADF has less documentation Oracle based ADF integrates well with Oracle Tools like Web Logic and DB etc Android and iOS need CSS change to accommodate Data driven app only good for ADF. No hardware access etc. Modules can be created using ADF (like a jar file) Multilingual Support is easier in non ADF

SHA belongs to the family of "Secure Hash Algorithms". You use the SHA functions to take any data like a document/password/text etc. and compute a "digest" or "hash" of the data. It's important to realize that this is a one-way process . You can't take back a hash/digest and get back the original data. MD5 or SHA are both crypto hash functions http://en.wikipedia.org/wiki/Cryptographic_hash_function       AES, on the other hand, is used to encrypt data, or prevent people from viewing that data with knowing some secret. AES is a family of functions called Symmetric-key algorithm that uses a shared key which means that the same key (or a related key) is used to encrypted the data as is used to decrypt the data at the receiver. This is different than Public-key cryptography family of algorithms that use a public key such PGP or SSL. http://en.wikipedia.org/wiki/Symmetric-key_algorithm

In the present day enterprise, the employees want access to the complete suite of enterprise applications. In addition to this, the network resources and any business tools they use at work are also needed on demand and that too on their devices of choice. A hunger for apps, data, resources and device independence, all these expectations add up to a requirement for a more creative enterprise enablement within the boundaries of the companies IT governance policies. Hence Mobile Device Management (MDM) has become of utmost importance for anytime anywhere access to enterprise data.   Companies use MDM to extend basic enterprise IT services like email, VPN and Wi-Fi access, while at the same time bringing devices under some form of control. When an employee leaves the company or a device is lost, MDM can restrict device usage that may leak proprietary data. MDM can wipe the entire device, including both corporate and personal data or also blacklist certain risky apps with cloud connectors

Thanks to our friend Rahul   The possible reasons would be:   1. iOS supports 5 service calls concurrently, this is a limit put from the OS. Advisable to make minimum amount of calls. 1-2 calls asynchronous, this will even help in low network speed. http://stackoverflow.com/questions/15089331/maximize-the-number-of-simultaneous-http-downloads Here is a library that deals with thread pool and URL dispatching just in case:  https://github.com/Weswit/utility-ThreadPool-ios   The article:  http://blog.lightstreamer.com/2013/01/on-ios-url-connection-parallelism-and.html     2. The above issue might be the root cause of the application crashing at certain points, call not handled properly. Application not receiving data since the network speed is slow, "request times out" not handled. 3. I'm guessing that the call are made asynchronous, if not then they should be made asynchronous or in background thread, a loader should be shown while this operation is performing. So that the

Specifically take care of the following   ·          Allocate Memory Using sizeof Never call malloc with an explicit size (for example, malloc(4)) to allocate space for a variable. Always use sizeof to obtain the correct size for any structure or variable you allocate. Search your code for any instance of malloc that isn’t followed by sizeof. ·          Always Define Function Prototypes ·          Take Care with Functions and Function Pointers   Here are more details on that https://developer.apple.com/library/ios/documentation/General/Conceptual/CocoaTouch64BitGuide/ConvertingYourAppto64-Bit/ConvertingYourAppto64-Bit.html
