Can you use NFS, or QNTC to connect to the Windows server? If so, what would prevent you from using CL, RPG, or COBOL to access the files on the Windows server and do all of the read/write stuff in said languages?

Maybe there is more to it that I understand but you could definitely read the files and write the files if you can connect via a file share. To me that would alleviate the overhead of doing HTTP requests to move the files around.

With a share, from an IBI i programming standpoint, the files would be part of the IFS.

Subject: [WEB400] Using HTTP\HTTPS to Transfer Files Between Servers?

We have a need to move stream files between the IBM i server and Windows servers.

I know I can use FTP. My question here is about what is possible. Since FTP and HTTP are both TCP/IP protocols, it should be possible to move files between the IBM i server and Windows servers using HTTP\HTTPS.

Suppose I have an Apache web serve set up on the IBM i server and an IIS web server set up on a Windows server. Here are the processes I want to accomplish.

FROM IBM i TO WINDOWS (INITIATED ON IBM i) 1. A COBOL or RPG program populates a DB2/400 physical file with data based on business logic.
2. A CL program uses the CPYTOIMPF command to create a stream file in the IFS based on the physical file.
3. A process on the IBM i sends a PUT or POST HTTP request to the IIS web server in order to move the file to the Windows server for storage.
4. A CL program uses the RMVLNK command to delete the file from the IFS.
How do I achieve step 3 above?

FROM WINDOWS to IBM i (INITIATED ON IBM i) Here is another process I want to achieve:
1. A process on the IBM i sends a GET HTTP request to an IIS web server to get a file and store it in the IFS.
2. A CL program uses the CPYFRMIMPF command to upload the file into a DB2/400 physical file.
3. A COBOL or RPG program then processes the DB2/400 file using business logic.
How do I achieve step 1 above?

I suspect I will be able to do the above processes with Node.JS on the IBM i. But I don't have Node.JS yet. So what other ways might I accomplish step 3 in the first process and step 1 in the second process?
