<br>
Can you tell us from which version you are upgrading to 6.3?<br>
<br>
I know that at some point header names parsing changed so that they'd<br>
have to be proper VCL symbols, leaving no room for otherwise valid<br>
HTTP headers that don't happen to match VCL expectations. We have no<br>
alternate syntax for "exotic" header names, I suggested req.http[7hello],<br>
someone else suggested req.http."7hello" but nothing happened in this<br>
direction. So your only solution today is to use vmod_header.<br>
