curl command return http/1.1 406 not acceptable error

php linux apache curl compression

Solution 1

In some case I had, faking the agent solved this problem, by using:

curl -A "Mozilla/4.0"

Similarly using libcurl C-API:

curl_easy_setopt(curl, CURLOPT_USERAGENT, "Mozilla/4.0");

Solution 2

From the HTTP/1.1 standard:

The resource identified by the request is only capable of generating response entities which have content characteristics not acceptable according to the accept headers sent in the request.

Unless it was a HEAD request, the response SHOULD include an entity containing a list of available entity characteristics and location(s) from which the user or user agent can choose the one most appropriate.

So drop the --head and you should see whats wrong.

The 406 may just be what is proving you right - the server doesn't support compression. :)

I am using below command line curl for knowing if my site supports compressing and caching

curl --head --compress http://www.mysite.com

it returns the following result
```

Date: Wed, 28 Dec 2011 07:41:32 GMT
Server: Apache
Content-Type: text/html; charset-iso-8859-1

I thought it would show more then just that. Anyway, 406 basically means "you asked for something I can't give you". curl --compress sends Accept-Encoding: deflate, gzip - apparently your server cannot serve that. In short: This response proves that your sysadmin is wrong, the server does not support compression. You can use curl's -v flag for more verbose output, inclusing the request-headers. That may help convince your sysadmin.

I had to use the full agent string "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2228.0 Safari/537.36", "Mozilla/5.0" didn't work. Thanks!

The faking agent worked exactly as provided, for me. Thank you!
