json - How to mod_rewrite based on http-header content-type -

is possible redirect user, based on http-header content-type?

for example:

1)

an application trying load localhost/res/123/var/abc , content-type set to:

application/json 

the server should return json-result application (which implemented).

2)

if normal web-browser visiting url localhost/res/123/var/abc, content-type set to:

text/html 

in case server should redirect browser output webview (e.g. index_web.html).

can realize without using php?

the content type not set @ request time, far aware. thus, need check if browser sending accept header, describes server kinds of data accept (and display) without downloading it. browsers this. send following header string server (this obtained chrome):

accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 

therefore, need check accept header using condition:

rewritecond %{http:accept} text/html [nc] # then, add rewriterules here ... 

this check see if text/html contained in accept header.
