IIS 7.5 WARN: No metatags found - works on apache server


#1

Hello great people of Twitter. How are you all today? I enjoyed a nice bowl of porridge for breakfast and recently had an apple, this was closely followed by an orange… But enough about me…

I am having issues with the validator and our IIS server.
html file on IIS 7.5 -
http://www.wales.nhs.uk/ogdata/media.html get the error - no meta tags found.
exactly the same file on Apache -
http://159.86.183.72/ogdata/media.html
This validates fine.

Can anyone throw any light on this please?

Thanks

Matt

It is something to do with the way that your IIS server is responding to our cards crawler’s user-agent (Twitterbot).

If I try curl -A Twitterbot http://www.wales.nhs.uk/ogdata/media.html the resulting page is a standard 404 / not found HTML page. Omitting the user-agent returns the page with the markup as expected. It might be an issue with request filtering in IIS.

Thanks Andy. I will take a look and get back to you!
