.htaccesshttp-redirecthttp-accept-header

specify and test htaccess HTTP_ACCEPT

When I test my .htaccess with

curl -H "Accept: application/rdf+xml" -L http://localhost/v0.1
curl -H "Accept: application/rdf+xml" -L http://localhost/v1.0

This works

RewriteRule ^v0\.1$ https://miranda-zhang.github.io/cloud-computing-schema/v0.1/ontology/cocoon.rdf [R=308,L]

But this doesn't

RewriteRule ^v1\.0$ https://miranda-zhang.github.io/cloud-computing-schema/v1.0/ontology.xml [R=308,L]

Without following redirection it returns:

$ curl -H "Accept: application/rdf+xml" http://localhost/v1.0

Solution

  • I think I have found what's wrong with your file. You are assuming that the "RewriteCond" that you have written for your first "RewriteRule" applies to the second one as well.

    However, this is not the case: you should repeat the condition for the second rule. For example, you have

    RewriteCond %{HTTP_ACCEPT} !application/rdf\+xml.*(text/html|application/xhtml\+xml)
RewriteCond %{HTTP_ACCEPT} text/html [OR]
RewriteCond %{HTTP_ACCEPT} application/xhtml\+xml [OR]
RewriteCond %{HTTP_USER_AGENT} ^Mozilla/.*
RewriteRule ^v0\.1/?$ https://miranda-zhang.github.io/cloud-computing-schema/v0.1/index.htm [R=308,NE,L]
RewriteRule ^v1\.0/?$ https://miranda-zhang.github.io/cloud-computing-schema/v1.0/index-en.html [R=308,NE,L]

    But in order to work properly, you should have

    RewriteCond %{HTTP_ACCEPT} !application/rdf\+xml.*(text/html|application/xhtml\+xml)
RewriteCond %{HTTP_ACCEPT} text/html [OR]
RewriteCond %{HTTP_ACCEPT} application/xhtml\+xml [OR]
RewriteCond %{HTTP_USER_AGENT} ^Mozilla/.*
RewriteRule ^v0\.1$ https://miranda-zhang.github.io/cloud-computing-schema/v0.1/index.htm [R=308,NE,L]

RewriteCond %{HTTP_ACCEPT} !application/rdf\+xml.*(text/html|application/xhtml\+xml)
RewriteCond %{HTTP_ACCEPT} text/html [OR]
RewriteCond %{HTTP_ACCEPT} application/xhtml\+xml [OR]
RewriteCond %{HTTP_USER_AGENT} ^Mozilla/.*
RewriteRule ^v1\.0$ https://miranda-zhang.github.io/cloud-computing-schema/v1.0/index-en.html [R=308,NE,L]

    If you don't, then it takes the rule without conditions, and serves the HTML every time you ask for "v1.0", as it happens in your curl command.

    I have tested locally the following file, and works successfully:

    Options +FollowSymLinks -MultiViews

AddType application/rdf+xml .rdf
AddType application/rdf+xml .owl
AddType text/turtle .ttl
AddType application/n-triples .n3
AddType application/ld+json .json

    When doing: 

    curl -sH "Accept:text/turtle" http://localhost/redirectTest2/v1.0

    I get:
