Hi,
I'm trying to understand why Chrome and MSIE get a different content
type via the tunnel than Opera, although the settings seem to be the
same. I'm using 2.0-RC4, and accept.properties [1] seems to have the
same settings for all the browsers.
User-agent tunnelling is enabled in the application using this:
getTunnelService().setUserAgentTunnel(true);
The request is done via jQuery/Ajax and I set the request's content type
with this:
beforeSend: function(xhr) {
xhr.setRequestHeader('Accept','application/json');
}
Firefox sends 'Accept: application/json' whereas MSIE, Opera and Chrome
send 'Accept: */*, application/json'.
The Opera user agent header is:
User-Agent: Opera/9.80 (X11; Linux x86_64; U; en-GB) Presto/2.5.24
Version/10.53
The Chrome user agent header is:
User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US)
AppleWebKit/533.4 (KHTML, like Gecko) Chrome/5.0.375.70 Safari/533.4
The resource uses:
@Post("form:html") postToHtml(Representation entity) { ... }
@Post("form:json") postToJson(Representation entity) { ... }
The content-negotiation seems to work fine in Firefox, Opera and MSIE,
but the HTML variant is selected when it's Chrome.
These commands returns a JSON representation (as expected):
curl -v -d 'var=value' http://localhost:8182/
curl -v -d 'var=value' -H 'Accept: */*, application/json' -H
'User-Agent: Opera/9.80 (X11; Linux x86_64; U; en-GB) Presto/2.5.24
Version/10.53' http://localhost:8182/
This command returns an HTML representation (not as expected):
curl -v -d 'var=value' -H 'Accept: */*, application/json' -H
'User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US) AppleWebKit/533.4
(KHTML, like Gecko) Chrome/5.0.375.70 Safari/533.4' http://localhost:8182/
When I change accept.properties to contains this, it works:
#Internet explorer
agentName: msie
acceptOld: */*, application/json
acceptNew: */*, application/json
agentName: msie
acceptOld:
acceptNew: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
#Opera
agentName: opera
acceptOld:
acceptNew: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
#Safari
agentName: safari
acceptOld:
acceptNew: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
#Chrome
agentName: chrome
acceptOld: */*, application/json
acceptNew: */*, application/json
agentName: chrome
acceptOld:
acceptNew: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
I'm confused regarding why Chrome and MSIE need this exception, whereas
Opera doesn't. Any ideas?
Best wishes,
Bruno.
