    ISAPI DLL concurrent requests

    Would you like to share some code? From what I learned about isapi from making xxm, it's important to catch any and all exceptions in your code, and not have them pass through into IIS as it can't properly handle Delphi exceptions and indeed may terminate the worker process. Typically you have a try except inside of every callback handler, the except clauses set an appropriate return value, but never re-raises, perhaps writes to an extra log.
  2. Just to be able to support TLS without the need for extra DLL's, I've used Windows' own 'SChannel' for a project once here.

    GZip compression in MARS

    Hmm, yes if it's static content, there would be sense in keeping a cache of the gzipped-data somewhere and serve that on subsequent requests. If it's dynamic content on the other hand, you might suspect this data to be one-off specifically for each request. So if there's a lot of it (and might take some time to generate, typically longer than it takes to transmit over to the client...) and you're having transfer-encoding chunked (which enables keeping the connection open when the response is sent over) then you should use TZCompressionStream's capability to zip a next chunk based on the existing stream...

    GZip compression in MARS

    Does MARS do streaming? Or does MARS do transfer-encoding chunked? (If so, you're apparently supposed to gzip first and then do the chunking...)

    his control requires version 4.70 or great of COMCTL32.DLL

    I remember Windows introduced manifest resources into exe files at some version and they also control the mapping to one of the versions of comctrl.dll that is present in the system. Could a manually modified .manifest file be causing this problem?

    Relaxed JSON

    I've been dabbling on a JSON parser that accepts pascal strings, and "=" instead of ":", and allows missing ","... https://github.com/stijnsanders/jsonDoc

    registering D6

    I rember something about old Delphi versions acting up when you've done some of the most recent windows updates. If I recall correctly, you need to delete a key "LM" under HKEY_CURRENT_USER\Software\Borland\Delphi\6.0 and then start Delphi to re-create that value with the right data.

    COM server to MARS

    I would respectfully request you to have a look at an alternative web platform I've been working on: https://github.com/stijnsanders/xxm It's not really designed to do REST endpoints, but all of the worker threads are COM enabled and also the main interface to generically connect all of the things any HTTP server environment offers is a COM interface. If I understand correctly, mapping each request to and from the different COM objects and their methods should be set up. This could be quite a manual task, or in the best case partially generated from scripts based on the IDL, but for a public facing HTTP endpoint it's important to do input sanitation and other security measures.
  9. I've noticed something strange with Delphi 10.3 update 2: If you have the IDE maximized, minimize it, and restore it again, the window appears to get narrowed a bit, even the "X" top right is no longer visible. Is that a bug that is recently introduced, or is this something I only get?

    HMAC_SHA256

    I copied the reference code for sha256 and hmac to Delphi once, have a look if you can make these work for you: http://yoy.be/md5.html

    Funny Code in System.Types

    Guys, are all of you missing this? Due to the Pascal calling convention, the first (plain!) argument of a function maps into the same register(s), so in fact this is valid and correct code. Though strictly I agree it looks weird and like as if in 'normal' cases the Value members aren't assigned to Result members. Bit in fact, they're already there! So what is actually needed is a 'type size limiting' cast, which is exactly what Result.x:=SmallInt(Result.x); is.

    LLVM static C objects triple need for IosSimulator

    Shoudn't that be "i686-apple-darwin-sim"? https://clang.llvm.org/docs/CrossCompilation.html

    I like alliterations, what about "total tire travel"? https://dictionary.reverso.net/german-english/Leistung

    DelphiTwain on 64-bit

    Even so, is TWINDSM.DLL you're using also 64-bits? (Is this the place to get current ones?)

    JSON string value

    Funny thing is, I recently had to think back at how I started with Delphi. Yes I did a bit of Turbo Pascal before, but I can't clearly remember what exactly it was I needed to get fluent in Delphi. As far as I can vaguely remember, it all did start with the documentation and the 'get stated' tutorial. Even if something like that covers the bases, the next step should be obvious. You should have enough knowledge to start a simple project. I remember my first Delphi project was a good old numbers to roman numerals converter. And I took off from there. (And about the initial discussion, sorry but I can't help it, I want people to know: If you know what you're doing, and really really need only the JSON and nothing extra, I've written my own no frills JSON parser here)
