Error in Safari

[Wilbur]

Hi all,

I got an error "Error loading document: Invalid XOD file: Zip end header data is wrong size" . When I replace my document with the document on http://pdftron.com/webviewer/showcase/ it works good. So I think this is should cause by my service to get xod files. I tried to add 

partRetriever.SetCustomHeaders({

   'If-None-Match': 'webkit-range-workaround'

});

 before the call to partRetriever.setErrorCallback and it doesn't work.

My service is written by Asp.net. My webviewer works good in all browser except safari  under iOS 7. And I know there is a bug in safari to post range request but it seems the issue of my webviewer not cause by this.

Some code of my service:

 fileStream = DigitalAssetUtilities.GetDigitalAssetReadStream(dynamicDigitalAssetReference.AssetConvertedUrl.ToString(), user, rangeHeaderValue, out contentRange, out acceptRanges);

                    response.Headers.Add("Accept-Ranges", acceptRanges);

                    response.Headers.Add("Content-Range", contentRange);

                    response.StatusCode = HttpStatusCode.PartialContent;

 Hope to get your help very much!

Thanks,

Wilbur

Hi Wilbur,

Unfortunately I don't have enough information to figure out the cause of this issue. If you could provide a link to access a document on your server then that would help with investigating the issue. If not then I would recommend closely comparing the headers and query parameters that are sent when accessing a document from your service and accessing a document from pdftron.com. If you want to post the request information here then I can take a look at them as well.
