Version History

Display:


v3.27.0.1

  • New : THttpRequest.OwnsContentStream property.
  • Improved : Modified logic for sending content using WinHttp, it was not working for the rare stream implementations that return a different number of bytes than requested even when stream data reading was not finished.

v3.26

  • New : Delphi 12 support.

v3.25.0.0

  • New : THttpRequest.ContentStream allows sending body via stream.
  • Improved : Support for ARM64 macOS and ARM64 iOS Simulator platforms.

v3.23

  • Improved : TSparkleJwtMiddleware.BeforeValidation event allows adding custom JWT validation rules.
  • Improved : Compress middleware now only compress response if the content is effectively compressible (text content type, javascript, JSON or XML).
  • Improved : Compress middleware now adds Vary header to the response for better caching of compressed and uncompressed responses.
  • Improved : Compress middleware does not compress if cache-control HTTP header is no-transform, or if content-range header is present.
  • Fixed : Middleware logging format string was wrongly parsed when a macro with parameter was close to another without any spaces (for example, :req[content-type]:req[content-type].
  • Fixed : HTTP client not correctly processing compressed responses (only relevant when accessing the in-process server).

  • Fixed : Forward middleware was showing up in the form as a non-visual component at design-time.

  • New : Sparkle.App.Console unit provides read-to-use server hosting app for Linux/Windows.

  • Fixed : JSON reader couldn't read content with a single byte (like 0 for example).

v3.14

  • New : TStaticModule.FolderUrlMode allows you to control how redirects work in URL representing folders. When user access an URL like /foldername or /foldername/, static module will check this property to decide if both addresses are different or one show redirect to the other.

v3.13

  • Improved : TSparkleHttpSysDispatcher.HttpSys property allows access to the internal underlying THttpSysServer object.

v3.7

  • Improved : Indy-based dispatcher now provides the correct URL scheme (http/https) and in consequence the correct default port (80 or 443) in the request URL. When receiving request through the Indy dispatcher, previous versions could not tell if the request was being made through HTTP or HTTPS protocol. The side effect was that the request URL schema was always being considered as HTTP and the port being 80. This is now improved, and if the request is coming via HTTPS, the default port of the request URL is now 443.

v3.6.1

What our customers say

As a developer for 30+ years, and a Delphi developer since 1996, I've a solid foundation on desktop development. But I was skeptical of indulging in web development. Though the market was demanding a switch, it seemed too difficult to make the transition. TMS Software was my "magic bullet" to get me started with zero intimidation. Love their Web Core and XData products. Now I can develop powerful web applications using Delphi. TMS Software has renewed my love for Delphi and won my heart for their innovators. Thanks to the team for great products and a large volume of demos and manuals. You ROCK!

- Larry

In the past I have purchased other components from other parties. I will say proudly that TMS is the best in support, price and style. Whenever I need a help your team is always there to help me. Keep up the good work

- Mohamed Thooloon

Hi Bruno Just want to drop you a line about how great your presentation was today. We often fail to point out to someone when they do a great job! You did a great job, you gave me a lot of ideas, and you answered my question very well. THANK you for your great products & super support.

- Lawrence Green

Thank you for developing components where I can best describe it like this: TMS components is a case where "The wheels fit the car, and NOT the car fit the wheels". Well done.

- Sathiparsad

As always your support is extraordinary and lightning fast.
