How to download non direct URL using HTTP ?

Question

Hi ,

 I ran the HTTP example of chilkat to download remote file. It works fine.
 Now my requirement is when I send a HTTP request to download a file.
  1. Server side it generates dynamically and doesn't store anywhere directly pass the file to HTTP request.

 when I do this manually it worked.

 But while programmatically. I got error.

 I am sending the chilkat log.

 **Log :**

            OK to ServerHelloDone!

The HTTP error code is 500, which means that the problem is on the server-side - are you sure you are using the correct parameters for the API in your code? Maybe you could post your source code?

The file is downloaded in streaming mode directly to the filesystem.

Is it possible using chilkat to get the stream using HTTP ? If required i will send the source code.

To be honest, I'm not sure - I'm just a fellow user, not a Chilkat employee, and I don't use streaming mode for HTTP. Maybe you should try with the QuickGet method, just to see if it works at all with the Chilkat component and debug your parameters for the server-side API that way. Once it works, then you can try the streaming method again.

It's important to include the information at the beginning of the LastErrorText because it gives context to the remainder of the information. In this case, it's important to know the version of Chilkat used. If it's an older version, it could be an issue that my have already been solved by updating to the latest version.

I agree with jpbro though, a 500 Server Internal Error points to a problem on the server-side. (Which doesn't necessarily mean that's where the source of the problem lies, but it just points in that direction and one would think it's more probable that the cause is on the server-side.)
