There are no simple solutions to supporting multiple cloud providers. The free ICS component library has the HTTP REST and OAuth2 support you need, and has components to access cloud email at Google and MS, so should not be hard to add support for cloud storage, but someone will have to dedicate a few days to supporting and testing each cloud service. Angus

Each of these cloud providers has its own REST API to access storage services. You can sign up to each of them, read loads of API documentation and write code using various REST components for each one, and hope they don't change the API too often. Or search GetIt for commercial components that have done all this hard work, and hope the authors keep them up to date as APIs change, TMS Software and /n Software come to mind, never used them myself.

I'll be testing using my own public proxy server, remembered I do have one http server, svn.overbyte.be. But I have some stuff to catch up with first. Angus

Thanks, I'll look at reproducing it on my servers, main problem is all my web sites are https only and force http to https, so needs something set-up for testing. Angus

To fix a bug I must be able to reproduce it. Sure the logs sure some different numbers, but I've no idea what data or requests you are sending, no headers logged or anything useful for debugging. Forward proxy is intended to direct to another web site, such as this one that generates a lot of data, very useful for testing in a live environment, the internals of the proxy moving data are the same for forward and reverse HTTP proxy. Angus

Nothing obvious missing, why did you create a certificate in the Windows store instead of a PEM/PFX that ICS would create for you? I find it better to test with real IP addresses, your server won't start if there are any web servers running on 80/443. The two logs look the same except for a couple of values, not sure what they are supposed to show. All my mail travels through TIcsProxy, and I use the Forward Proxy on my public servers to access my local servers remotely, so the component is well tested, and rarely touched to break it Angus

TStringList handles most requirements for CSV handling with the CommaText method, you can change the delimiter if needed. You read one line at a time into TStringList.CommaText and get one line per column, or vice versa to create a CSV record. The file can be read or written with a second TStringList or sequentially with normal file handling code if large. Angus

What specific new features and performance improvements are you looking for? What is the business case for the major effort a migration would involve? This is many weeks or months of work, and retesting. All your other questions have been covered in detail over the last 15 years as others have migrated from non-unicode compilers to modern Delphi. I've just released a new version of one of my products built with Delphi 2007 because of third party component problems with Delphi 11. The end users don't care. Angus

OpenSSL has released new versions of the active versions, 3.3.1, 3.2.2 and 3.0.14 which have several low priority security fixes. Windows binaries are available in SVN and the overnight zip file and separately from https://wiki.overbyte.eu/wiki/index.php/ICS_Download or https://www.magsys.co.uk/delphi/magics.asp In addition to the three DLL files, the zips include compiled RES resource files that contain the same DLLs, text files and version information, see the RC file. The RES file may be linked into application EXE files and code then used to extract the DLLs from the resource to a temporary directory to avoid distributing them separately. ICS V9.1 and later optionally support loading the resource file. These OpenSSL versions are included with ICS V9.2 due for release in a few days, but available from SVN and the overnight zip. Separately, YuOpenSSL has released 3.0.14 as commercial DCUs allowing applications to be used with OpenSSL without needing separate DLLs. Note: OpenSSL also released 3.1.6, but this ceases support in less than a year and has two newer releases, so we've stopped building binaries for it. 3.0.14 is a long term support release so is still being built. Angus

Your management may need to concede that the components offered by Embarcadero are often missing features in third party components, which is why there are so many of them. Angus

You are not using the modern REST component TSslHttpRest, but the older harder to use component TSslHttpCli, your choice, but you have to live with more complex code. The point here is that you are responsible for determining whether you successfully connected to the HTTP server, and cleanly close everything if not, and try again. ICS is event driven, it does not wait x seconds and then decide to clean everything up for you, not even the sync modes. There will be no breaking changes to the way the HTTP client handles errors, without weeks of discussion. You need to handle this yourself. Angus

This was fixed for V9.2, in SVN and the overnight zip. Are you using one of those? Angus

If your error handling code does not correctly clean up after errors, you can check , Before starting a new request, you can check State <> wsClosed before starting a request and close it. Beware, Close may not be instant, if Windows is still attempting to connect. Angus

X509_get_X509_PUBKEY was added to OverbyteIcsLIBEAY;.pas for V9.1, so you probably have mixed versions, with old and new units. Angus

To my eye, the two procedures seem to be identical, so I can only assume the different result is due to different parameters to the two procedures. BTW, since you are using the RawParams option in RestRequest, RestParams are ignored. Angus

Authentication should now be fixed in SVN and the overnight zip. Angus

AnswerBodyTB is now in SVN and overnight zip updated. Angus

That was fixed in V9.1, or at least there are now settings that allow the HTTP clients to be used without SSL being available, for http:// only. I go to extreme lengths to keep ICS backward compatible, I know how horrible it is updating to new compilers and components when you get blizzards or IDE error messages on opening old projects, it's why some of my projects are still Delphi 2007. Rarely backward compatible is not possible, but I did spend a week or two writing documentation and updating samples explaining how to update to V9.1. Angus

The default defines are designed so that users get new applications working easily and safely, without them failing immediately because the OpenSSL DLLs can not be found. Or needing to copy those DLLs into every single different directory to which modern versions of Delphi build by default. Angus

If you undefine {$DEFINE OpenSSL_Resource_Files}, ICS will look in the ICS-OpenSSL directory for the DLLs, so how does make you in control? If you want to load the DLLs from your own specified location, like the application directory, you need to add extra code, as has always been the case with ICS, but you'll need to change other defines as well since OpenSSL is now loaded by default before any code is run. This is explained in depth in readme9, and other places. Angus

No, ICS will never contain an openssl-x64.exe file, since ICS does not use openssl.exe. Our OpenSSL zip distributions are separate for Win32 and Win64, so it is up to end users to do something if they want to combine them. SVN and the overnight zip do now correctly have the Win32 version of openssl.exe, the Win64 version was an error. Angus

Thanks, I'll install them in D12. Happy to update to the latest version, but some advice for existing would be appreciated, other than all the component names have 6 on the end. Or is it simply a case of going through the DFM and PAS files with a text editor and adding that 6 to the types. Angus

ICS house style, per your original request example. Angus

Thanks, I added AnswerBodyTB which creates a TBytesStream, not tested yet since the samples don't send small streams. Angus

Do you expect AnswerBytes to be an alternate to AnswerStream, AnswerString or AnswerPage? Angus
