    <p>I have an MVC application view that is generating quite a large HTML table of values (>20MB).</p> <p>I am compressing the view in the controller using a compression filter</p> <pre><code> internal class CompressFilter : ActionFilterAttribute { public override void OnActionExecuting(ActionExecutingContext filterContext) { HttpRequestBase request = filterContext.HttpContext.Request; string acceptEncoding = request.Headers["Accept-Encoding"]; if (string.IsNullOrEmpty(acceptEncoding)) return; acceptEncoding = acceptEncoding.ToUpperInvariant(); HttpResponseBase response = filterContext.HttpContext.Response; if (acceptEncoding.Contains("GZIP")) { response.AppendHeader("Content-encoding", "gzip"); response.Filter = new GZipStream(response.Filter, CompressionMode.Compress); } else if (acceptEncoding.Contains("DEFLATE")) { response.AppendHeader("Content-encoding", "deflate"); response.Filter = new DeflateStream(response.Filter, CompressionMode.Compress); } } } </code></pre> <p>Is there a way to also eliminate the (quite large) amount of redundant whitespace generated in the view before I run the compress filter (to reduce compression workload and size)?</p> <p><b>EDIT:</b> I got it working using the WhiteSpaceFilter technique suggested by Womp below.</p> <p>For interest here's the results, as analysed by Firebug:</p> <p>1) No Compression, no whitespace strip - 21MB, 2.59 minutes<br/> 2) With GZIP compression, no whitespace strip - 2MB, 17.59s<br/> <b>3) With GZIP compression, whitespace strip - 558kB, 12.77s</b> <br/> <br/> So certainly worth it.</p>

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
