<div dir="ltr">Hi,<div style> We have a proprietary dns client that communicates with DNS resolver which is using unbound proxy. We have the need to encode some metadata and place it as part of query itself. </div><div style>
<br></div><div style>For e.g. request for <a href="http://www.microsoft.com">www.microsoft.com</a> will be changed in client to www.microsoft.com.mymeta. Then in mymodule_operate we would do some custom filtering based on mymeta and then strip out ".mymeta" to the next module, iterator.</div>
<div style><br></div><div style>1. Could you point me to some sample code that does this kind of processing?</div><div style><br></div><div style>2. Also, how would caching behave in the above model?</div><div style><br></div>
<div style>3. On a related note, I assume we can use EDNS for passing such metadata. When is unbound support for EDNS with apis for extracting such data from OPT records planned? </div><div style><br></div><div style>I am currently using version 1.4.19 of unbound</div>
<div style><br></div><div style>Thanks much</div><div style>Mani</div></div>
