Hello,

I have the following code to export a zip file:

byte[] buffer = FileUtil.FileToByteArray(zipLocation, true);

// push the memory data to the client.
_ctx.Response.ContentType = "application/zip";
_ctx.Response.AddHeader("content-disposition", String.Format("attachment; filename={0}", String.Format("map{0}.zip", mapId)));
_ctx.Response.BinaryWrite(buffer);

This code works great. After every export I get a perfectly made zipfile. The problem however is that when I try to import it, the mimetype sometimes is "application/empty".

Now I wonder how can I ensure that the mimetype is always added?

Cheers, M.
