The document summarizes key differences between various web development concepts. It compares HTTP and HTTPS, describing how HTTPS provides encryption and uses port 443 while HTTP does not encrypt and uses port 80. It also compares GET and POST methods, noting that GET requests are in the URL while POST requests send data in the HTTP body. Finally, it outlines differences between user controls and master pages, generic handlers and HTTP handlers, and building versus rebuilding in a solution. The document provides a helpful reference for understanding common web development concepts and how they differ.

Some comments on the limit on QueryString / GET / URL parameters Length:
1. 255 bytes length is fine, because some older browser may not support more than that.
2. Opera supports ~4050 characters.
3. IE 4.0+ supports exactly 2083 characters.
4. Netscape 3 -> 4.78 support up to 8192 characters.
5. There is no limit on the number of parameters on a URL, but only on the length.
6. The number of characters will be significantly reduced if we have special characters like spaces
that need to be URLEncoded (e.g. converted to the '%20').
7. If we are closer to the length limit better use POST method instead of GET method.](https://image.slidesharecdn.com/asp-netdifferencefaqs-4-120802110658-phpapp01/85/Asp-Net-difference-faqs-4-2-320.jpg)

- 1. 1.Difference between HTTP and HTTPS S.No HTTP HTTPS 1 URL begins with “http://" in case URL begins with “https://” in case of of HTTP HTTPS. 2 HTTP is unsecured HTTPS is secured. 3 HTTP uses port 80 for HTTPS uses port 443 for communication communication. 4 HTTP operates at Application HTTPS operates at Transport Layer. Layer 5 No encryption is there in HTTP HTTPS uses encryption. 6 No certificates required in HTTP certificates required in HTTPS. 7 Most internet forums will HTTPS should be used in Banking probably fall into this category. Websites, Payment Gateway, Shopping Because these are open discussion Websites, Login Pages, Emails (Gmail forums, secured access is offers HTTPS by default in Chrome generally not required browser) and Corporate Sector Websites. For example: PayPal: https://www.paypal.com Google AdSense: https://www.google.com/adsense/ 2.Difference between GET and POST methods S.No GET POST 1 Post Mechanism: Post Mechanism: GET request is sent via URL. Post request is sent via HTTP request body or we can say internally. 2 Form Default Method: Form Default Method: GET request is the default We have to specify POST method method. within form tag like <Form method="POST"....... 3 Security: Security: Since GET request is sent via Since Post request encapsulated name URL, so that we can not use this pair values in HTTP request body, so method for sensitive data. that we can submit sensitive data through POST method.

- 3. 3.Difference between User Controls and Master Pages S.No User Controls Master Pages 1 Its extension is .ascx. Its extension is .Master. 2 Code file: .ascx.cs or .ascx.vb code file: .master.cs or .master.vb extension 3 A page can have more than one Only one master page can be assigned User Controls. to a web page 4 It does not contain It contains ContentPlaceHolder. Contentplaceholder and this makes it somewhat difficult in providing proper layout and alignment for large designs. 5 Suitable for small designs(Ex: More suitable for large designs(ex: logout button on every .aspx defining the complete layout of .aspx page.) page) 6 Register Tag is added when we MasterPageFile attribute is added in drag and drop a user control onto the Page directive of the .aspx page the .aspx page. when a Master Page is referenced in .aspx page. 7 Can be attached dynamically Can be referenced using Web.Config using LoadControl method.PreInit file also or dynamically by writing event is not mandatory in their code in PreInit event. case for dynamic attachment. 4.Difference between Build and Rebuild S.No Build Rebuild 1 A build compiles only the files A rebuild rebuilds all projects and files and projects that have changed. in the solution irrelevant of whether they have changed or not. 2 Build does not updates the xml- Rebuild updates the xml- documentation files documentation files Note: Sometimes,rebuild is necessary to make the build successful. Because, Rebuild cleans Solution to delete any intermediate and output files, leaving only the project and component files, from which new instances of the intermediate and output files can then be built.
- 4. 5.Difference between generic handler and http handler S.No Generic Handler Http Handler 1 Generic handler has a handler http handler is required to be which can be accessed by url with configured in web.config against .ashx extension extension in web.config.It does not have any extension 2 Typical example of generic For http handler, page handler which handler are creating thumbnails of serves .aspx extension request and give images response.
