Ic, <span style="border-collapse:collapse;white-space:pre-wrap">Poul-Henning</span> thank you!<div><br></div><div>
Hey guys,<br><div><br></div><div>Im still trying to get a handle how to debug these vcl rules best here..</div><div><br></div><div><a href="https://gist.github.com/ca5ef043fdfb89a5b143" target="_blank">https://gist.github.com/ca5ef043fdfb89a5b143</a></div>
<div><br></div><div>Ive got some simple tests set up, mainly based on <a href="http://overstimulate.com/articles/varnish-getting-started" target="_blank">http://overstimulate.com/articles/varnish-getting-started</a></div>
<div><br></div><div>
With app #1 caching happens fine, but with app #2 with the same very general vcl rules, I cant seem to get caching to work :(.</div><div><br></div><div>There's a few questions at the end of the gist:</div><div><div>1. Why isnt app #2 picking up the cache? I think maybe the rails app returns a slighly </div>
<div>different header that could be causing a problem but I dont see anything different in the </div><div>varnishlog output :(.</div><div>2. Is there a way to check what is in the cache from the "telnet localhost 6082" or anything </div>
<div>else, if I have the key, "/articles;feed?tag_id=16" in this case. Maybe thats whats going on, </div><div>the data isnt being written into the cache...</div><div>3. I also tried adding some C code (commented out) to maybe puts some output out or writing to </div>
<div>a file (maybe through a system call could work too) to see which part of the vcl chain Im </div><div>hitting. Whats a good way of doing that? This would be great to know how to do so I can </div><div>check the vcl rules. </div>
<div> </div><div><br></div><div>Thanks again and any responses are appreciated.</div><div>Tung</div></div><div><br><div><div><div></div><div class="h5"><br><div class="gmail_quote">On Sun, Mar 22, 2009 at 2:08 AM, Poul-Henning Kamp <span dir="ltr"><<a href="mailto:phk@phk.freebsd.dk" target="_blank">phk@phk.freebsd.dk</a>></span> wrote:<br>

<br>
</div>The first column is a magic number for each transaction.<br>
<br>
This is what allows you collect all the messages that<br>
belong to the same transaction.<br>
<br>
For the time being, it is also the file descriptor number<br>
of the socket, but this is not guaranteed to always be the<br>
case.<br>
<br>
The 'b' means "backend transaction, and 'c' client side<br>
transaction.<br>
<div><div></div><div><br>
> 7 VCL_return c pass<br>
>10 BackendOpen b default 127.0.0.1 57141 0.0.0.0 3000<br>
> 7 Backend c 10 default default<br>
>10 TxRequest b HEAD<br>
