Hi guys,<br>Just wanted to give you a heads up that yesod&#39;s sendFile is not setting the Content-Length header, which &#39;breaks&#39; some proxies and load balancers. (in our case, amazon elastic load balancer).<br>I don&#39;t know if that&#39;s by design, I&#39;m not 100% sure but not setting the header would be only useful for &#39;long pooling&#39; of binary files for doing some sort of hackish http streaming, which I don&#39;t think is yesod&#39;s purpose anyways :)<br>
A workaround is setting the Content-Length header before calling sendFile, I guess it may be something easy to add, I was going to propose a patch that just wraps the current implementation in a do block that sets the header, but then I noticed a number of optimizations being made that hint there should be a &#39;better&#39; way.<br>
