Hi all,

So it seems that our website is experiencing caching issue in which a PDF is opened by an user on the site.

This PDF creates a cached file in the form of "u3dtncra.pdf" and other variations at random.

The cached file is then presented to the user.

So since we have heavy traffic during press releases this is filling up our webstorage fast.

How can I stop this?

Umbraco is set up to show the PDF embeded in the site like so:

@foreach(var temp in myList.Select((value,i) => new {i, value}))
{   
    if(@temp.i == 1)
    {

        if(@temp.value == null)
        {
            <p>No image</p>
        }

        else
        {
            <td class="col-sm-2">
                <a href="@item.Url">
                    <img height="100" width="100" class="img-rounded img-responsive" src="@Umbraco.TypedMedia(@temp.value).GetPdfThumbnails()"/>
                </a>
            </td>
        }
    }
}

It works without any problems, the PDF shows itself nicely, but the caching is filling the drive.

Any ideas on how I can disable the caching?

Thank you,

Laurens
