Hello everyone,

I was wondering if anyone else gets this Repository error in their log files? I'm using DNN 3.2.2 with Repository 3.01.09.

Can anyone tell me whether this is fixable or not? Also, how severe is it?

Thanks in advance,
Rose

Yes, I get this error for every download of a file as well. I've looking into this. It seems to have to do with calling:

HttpContext.Current.Response.Clear()
HttpContext.Current.Response.ClearHeaders()
HttpContext.Current.Response.ClearContent()

which occurs in Download.aspx.vb DownloadFile() method.  However, looking at the source code, that seems to have been replaced by a call to StreamFile(). So, the released DLL in 3.01.09 is behaving like the older code was compiled, then the newer version was included in source code package.

I recompiled the source so it would now use the StreamFile() method and now I get other types of errors. I think due to use of  System.IO.Stream in a medium trust environment.

So, its my belief that the released DLL of Repository 3.01.09 is called DownloadFile() which triggers the cookie error and that the new version of the source code has different flaws.

I'm going back to the 3.01.09 DLL for now and just living with the errors in the error log.

The biggest problem with that error is that it's hit and miss. I've got two production installs of DNN using seperate databases. On install hosts around 4 small sites while the other one only hosts one big one and only saw the error on one of the installs. That said, it's fixed in the next release of the Repository.
