ETag Support in IE6/IE7 on Windows XP

[sknipe]

IE does not send the If-None-Match : ETag values as defined in the HTTP
specifications. This is supported by FireFox.

IE:

Request Header:

Is there something wrong with the http headers or is there a known
workaround?

Thanks,

Steve.

IE supports that.

My guess would be that these headers may be inhibiting it.

X-Cache MISS from bw-s1.blogware.com
X-Cache-Lookup MISS from bw-s1.blogware.com:80

Can you try suppressing those headers for this User-Agent?


Good luck
