Web Applications





Web applications are systems that run in browsers that perform functions normally associated with other client-based programs. One of the most commonly used web applications is email; instead of downloading individual emails to a local machine, the data is shown through a website. Other examples of web applications are collaborative systems like a wiki or an online game.

I am keeping this generic - so that some may suggest something 'Out of the Box' that may lead to a technique/tool/approach being suggested.

I have a client that uses a 3rd party IIS based application running from an internal server and uses a MS SQL Db underneath.  The SW vendor is having problems with it randomly stalling servers for the last 2 yrs :( and is stuck trying to resolve it) and it took them 18 months to admit it was affecting other customers   > :(

On ocassion it loads up the OS to the point that ASR cuts in and reboots the server, which is handy (but not desirable) given the OS becomes totally inaccessible.  There are times (like today) where I get enough notice that its having a moment, that I can log in and gather information on what is going on.  I usualy go to IIS manager and stop/start the respective App pool.

I have used
  1. Event log information
  2. Perfmon to gather huge data on the W3WP process and subordinates.
  3. IIS to list currently active worker processes and their Request State details for the vendor.
  4. Ran a dependency trace on the W3WP.exe and relevent application specific DLL's to weed out missing/outdated dependencies
  5. Used some of Idera's SQL analysis tools to check on what the DB is "hearing" and doing.

So, throw me something I havent thought of that may be worth a try.  The SW vendor is a decorated MSFT developer so I expect they've got access …

We are working on implementing Microsoft's MultiFactor authentication within our organization. When modern authentication is enabled in the Office 365 portal it seems to effectively block Cisco Jabber/Webex outlook integration with Outlook.

We need to be able to enable to MFA in some capacity for both Outlook 2016, Office 365 Web applications and retain Cisco product integrations.

I'm having some difficulty finding information on compatibility or "howto" information on how to get this working accordingly. Any help would be appreciated.

I have a pretty short timeline to implement this solution.
Guys, I am trying to see the websites that are referring to a particular domain and be able to go back and view them. I am trying to see the content of the referring sites. Does anyone have suggestions for tools that will show you the addresses referring to a particular domain?
I've got a client who's domain was registered by a former employee. The former employee has turned off their website and wont give access to the account on GoDaddy to control the domain. Does anyone know what he needs to do in order to prove ownership of the business so he can regain control over his domain?
Hello, experts!

I need some advice in terms of legacy Data migrating into a new cloud environment.

Our business rules use repair orders (tickets) that contain job and part data for every ticket. the life cycle of a ticket is customer comes in > address concern > ticket is created > presented to customer and approval is given by customer > ticket finalized. Let's play out a scenario, let's say someone comes in for an oil change and the inspection of the vehicle turns up a timing belt issue. Issue is presented to customer and customer does not approve that work - only the oil change. That timing belt denial becomes a saved estimate in the system which could be used later down the line to try to earn business to do that work.

Fast forward to migration of new system. We are bringing in finalized data into our new environment and this "saved estimate" data is crucial. The current system uses a +1 increment with the generation of RO (repair order) #s. So if we were to migrate saved estimates (they have their own set of RO#s in the legacy system), there might be a gap or a collision of RO#s in the future. Ex: system is counting at 9001 and incrementing.

What is the best way to handle bringing in this saved estimate data? Should I bring the data in as a searchable object so that if someone wants to see what someone's saved work and generate a new ticket it's view only so that the end user can then just create a new ticket and read only the data of the saved estimate?

Hi All,

I'm a very rusty programmer who has opportunity to get nice business but need to get in shape pretty quickly.

I was programming like 8 years ago, mainly in C# Windows Forms and was pretty good at it. I still remember it.

Today I'm about to create cloud application where I need:
- nice web front end. Interactive application, wizard
- frontend will send files for remote computing on my server (my PC with C# application, Windows for sure, no Linux absolutely)
- server will compute and generate .pdf (how to generate pdf...?)
- pdf accessible in frontend for download and sent via email
- frontend will ask for payment before computing. Subscription plans 24h access, 6 months, 12 months

More or less I think its good description.

I need to choose technology I will use which is easiest for me to adapt.
ASP.NET or HTML5 or what is at the moment most desirable?
I wish to program in Visual Studio Pro.
I hope I don't need to learn anything more than I need for this project.

Please advise!

Many Thanks!
Dear All ,

I am having problem while publishing a web application under a virtual directory on IIS.
below is the message i am having , while working on the http after a while
There was no endpoint listening at "http://localhost/Myservice" that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if
present, for more details
Please help me .
Thank you
Have a client that has a virtual assistant company, as a call comes In that client profile comes up in his system, at some clients he needs to connect to a computer at the client's since he needs to use a locally installed application, I would recommend him to you RDP but since the system he uses only accepts a URL, is my question is there is a way to launch RDP with a URL?
Or you may have any method of connecting to suggest
Client has asked me to provide some idea about how to duplicate the http://playspent.org/ gamification system.

If someone knows of a system like this in the wild which might be used to duplicate a similar site, let me know.

Something beyond simple systems like https://github.com/mulhoon/score.js providing layout of badges + count accumulation buckets in a response style system.

Maybe some sort of bolt onto score.js using SVG graphics for presentation.

We have a NetCore web application and we are looking for an SDK or REST API that will parse data in PDF files.
If we upload a PDF file with specific fields we need for the PDF Parser to extract the data in those fields and arrange it into XML or JSON so that we can then use it any way we want.

I found a couple software companies that have this type of PDF Parser but I want to do more research on this. Any recommendations?  Do you have any experience with the recommended software?

Is there an easy way to set up shortcuts using your own domain (but not break or involve the existing website)?

Say the domain is mydomain.com.  People currently can type mydomain.com or www.mydomain.com and it goes to the website.

I'd like to be able to set up shortcuts / redirects so  something like time.mydomain.com would redirect to a specific website (in this case, maybe www.time.gov).

This is for someone else.  A long time ago I found a perl script that I put on my website, called it index.cgi, and it had this info:

$mainpage       = "index.html";
%domains = (      
'www.mydomain.com'          =>  'https://www.mydomain.com',      
#enter shortcuts here      
'time.mydomain.com'         =>  'http://www.time.gov',

#end of shortucts

'www.mydomain.com'          =>  'http://www.mydomain.com/index.html'      
$server = lc($ENV{'HTTP_HOST'});if ($ENV{'HTTP_HOST'} =~ /(\d+)\.(\d+)\.(\d+)\.(\d+)/){$t='/'}else{if ($server !~ /^www./){$server = '' . $server;}}@domains = keys(%domains);foreach $domain(@domains){if ($domain eq $server){print "Location: $domains{$server}\n\n";$match="yes";last;exit}}unless($match){print "Location:  https://www.mydomain.com/index.html\n\n";exit}exit;      
That does what I'm asking about - enter loads of shortcuts and you can enter that subdomain and it takes you to the appropriate webpage.

Are there other ways via the DNS zone record or something else?  

Are there simpler ways to do this redirect of …

We recently moved our business application from windows to web (.NET, jquery, javascript). The transition was very difficult especially for the Sales Department who complained that the web application was too slow comparatively. The other issue with the web application was it would get stuck if the user was idle for more than 2 minutes until he refresh the screen. This issue was highly resolved after we moved from Chrome to Firefox.

The dilemma we are in right now is about some external apps that we need to migrate. The things that these apps do are pretty important like: Creating invoices, converting hold order to confirmed orders, price the products e.t.c.
These application are currently written in VB6 and can be run only on 2008 servers. We need to upgrade them.. For user satisfaction, I would really like to create them as windows application. But is it taking a step backward? Are there any advantages to web applications that I need to consider?

Can you please advise?
Our company is using Microsoft Azure for our employees. We have a web application that uses Azure to authenticate our users. Just recently Multi Factor Authentication was enabled through Azure for our users. As a result this makes the users have to put in a password and then get a text message or phone call to authenticate them for this web application. My question, is there a way to exclude Multi Factor Authentication for a specific url?
Our wiki is run off of this platform... Which i am totally new on this so bare with me if this is a silly question. But I hope to find someone who can tell me how to fix it or something that i can run to fix it. any suggestion would be greatly appreciated

I'm looking for an option to create a custom HTML element like below:
<content-entry content-type="news" as="entry"  id="1" > 
        <h1> {{entry.title}}

Open in new window

Expected behavior:

custom element named "content-entry" should encapsulate the logic of calling my content api to fetch the "News" with an Id matching as "1". It should return new object and it should be accessible as "entry" so that it can be used for further operations e.g. printing title, description etc.


Ideas is to hide and encapsulate component specific implementation logic and make a re-usable component.

It would be greate if you anyone can help me or guide me with appropriate solution.

I was just wondering if there is a specific title for someone that plans/designs a web application/development System Architecture? What are they called in the industry and how would you go about hiring one? I need someone to help guide us in the right direction when it comes to both the hardware and software architecture in a consultancy capacity but what is that job title, is it the simple the web developer or engineer that does that or is it an entirely different role?


I was wondering if anyone could help me with what I hope is not a stupid question. If you are developing applications that are need to run a website and some of the applications can be run as microservices and some as serverless applications but some must be run on monolithic architecture styles, so basically a hybrid approach, can you develop all applications on the same technologies within containers and then deploy across Microservices, Serverless and Monolithic as needed?

Hi,  I'm creating a PHP and MySQL web application for a client. I'm a fairly new web developer.
Is there a way to add page titles and meta tags dynamically? It's a small application. I'm not using a Framework.
I saw a couple of possible solutions on google, but am not sure what the easiest and most efficient way of doing it would be.

Possible Solution #1, add variables in my header.php page and then on each respective page for example about, contact etc... add those variables above the include statement.
Here is my header.php code:
