Dispatcher Redirecting request for fonts to 404 error pages

Hi All,

 

I have the below scenario - 

 

1. CSS clientlibs file calling font files via url syntax as below - 

@2375939-face{
font-family:icomoon;
src:url(clientlib-site/resources/icons/icomoon.eot?s69qo9);
src:url(clientlib-site/resources/icons/icomoon.eot?s69qo9#iefix) format("embedded-opentype"),
url(clientlib-site/resources/icons/icomoon.ttf?s69qo9) format("truetype"),
url(clientlib-site/resources/icons/icomoon.woff?s69qo9) format("woff"),
url(clientlib-site/resources/icons/icomoon.svg?s69qo9#icomoon) format("svg");

}

 

2. Behavior on Publish and Dispatcher - 

Publish - The clientlibs and the files (ttf | woff) are displaying 200 OK when hit.

Dispatcher - The clientlibs file is correctly hit but the icon files are redirecting to 404 pages.

 

Fixes Tried - 

1. Updated the VHost configuration to turn on ModMimeUsePathInfo.

ModMimeUsePathInfo On 
<IfModule mod_mime.c>
    AddType application/vnd.ms-fontobject    .eot
    AddType application/x-font-opentype      .otf
    AddType image/svg+xml                    .svg
    AddType application/x-font-ttf           .ttf
    AddType application/font-woff            .woff
    AddType application/font-woff2           .woff2
</IfModule>

 

Can you please help why the dispatcher would redirect the font request to error page with 301 ?

The other clientlibs request for CSS and JS are loading fine, the publisher is downloading the font icon when directly hit.

    Hi All,

     

    The problem is now resolved.

     

    Checking the Publish's Error Log I found the issue below - 

    14.08.2022 08:10:09.651 [cm-pxyxyx-eyyyyyy-aem-publish-54abcdefd9-rxms2] *INFO* [122.177.105.119 [1660464609650] GET /etc.clientlibs/brandA/clientlibs/clientlib-site/resources/icons/icomoon.ttf HTTP/1.1] com.adobe.granite.ui.clientlibs.impl.ClientLibraryProxyServlet Proxy request to /etc.clientlibs/brandA/clientlibs/clientlib-site/resources/icons/icomoon.ttf not supported.

     

    The sling mapping for etc.clientlibs was missing in dispatcher which solved the issue.

    Hi @rohan_garg ,

    I believe it must be issue with rewrites. Can you please share the full path of the sample file (e.g. icomoon.ttf)

      CSS File - 200 OK both on dispatcher and publish

      https://publish-pabcde-exyzabc.adobeaemcloud.com/etc.clientlibs/brandA/clientlibs/clientlib-site.lc-4475042b57b4e02f2f8147fe0b49fb14-lc.min.css

       

      File URL - 200 OK on publish, 301 on dispatcher then error page 404

      https://brandA.com/etc.clientlibs/brandA/clientlibs/clientlib-site/resources/icons/icomoon.ttf?s69qo9

        Please find below the sample rewrite (for testing). The below rewrite would be applicable to shortened urls and ends with only .html extension

         

        #Redirect for all the shortened pages with html

        RewriteCond %{REQUEST_URI} !^/?(etc.clientlibs|resources|libs|content|libs|apps) [NC]

        RewriteCond %{REQUEST_URI} ^/(.*).html$

        RewriteRule ^/(.*) /content/<projectname>/us/en/$1 [PT,L,QSA]


        I tested on the https://technicalseo.com/tools/htaccess/ all my rewrite rules to see if any can interfere with my request URL - none of them is passing the rewrite conditions or passing the rewrite rule criteria.

        Request URL - https://domainA.com/etc.clientlibs/domainA/clientlibs/clientlib-site/resources/icons/icomoon.woff?s69qo9

        The initiator for this resource is a clientlib min.css file which is being handled by dispatcher correctly - 

        https://domainA.com/etc.clientlibs/domainA/clientlibs/clientlib-site.lc-4474712b67b4e02f2f4673fe0b49fb14-lc.min.css

         

        All Rewrite Rules in sequence - 

        1. # Add .html extension when extension is missing from request
        RewriteCond %{REQUEST_FILENAME} !-d
        RewriteRule ^([^.]*[^./])$ https://%{SERVER_NAME}$1.html [R=301,L]

         

        2. #Rewrite for Root Direction

        RewriteRule "^(/?)$" "/content/brandA/us/en/home.html" [PT,L]

         

        3. Rewrite for URL Shortening

        RewriteCond %{REQUEST_URI} !^/apps
        RewriteCond %{REQUEST_URI} !^/bin
        #RewriteCond %{REQUEST_URI} !^/content
        RewriteCond %{REQUEST_URI} !^/etc
        RewriteCond %{REQUEST_URI} !^/libs
        RewriteCond %{REQUEST_URI} !^/saml_login
        RewriteCond %{REQUEST_URI} !^/system
        RewriteCond %{REQUEST_URI} !^/tmp
        RewriteCond %{REQUEST_URI} !^/var
        RewriteCond %{REQUEST_URI} (.html|.jpe?g|.png|.svg|.xml)$
        #RewriteRule ^/content/brandA/us/en/(.*)$ /$1 [NE,L,R=301]
        RewriteRule ^/content/brandA/us/en/(.*)(\.html)?$ https://%{SERVER_NAME}/$1 [NE,L,R=301]

         

        4. #Replace the .html with /
        RewriteCond %{REQUEST_URI} \.html$
        RewriteRule ^/(.*).html$ https://%{SERVER_NAME}/$1/ [R=301,L,QSA]

         

        5. #Append the .html for those URL’s ending with / before sending to publisher
        #This rule should not work for requests originating with non /content/brandA domains and should also work for shortened URLs
        RewriteCond %{REQUEST_URI} !^/content/brandB
        RewriteCond %{REQUEST_URI} !^/$
        RewriteRule ^/(.*)/$ /content/brandA/us/en/$1.html [PT,L,QSA]

         

        6. RewriteCond %{REQUEST_URI} !^/apps
        RewriteCond %{REQUEST_URI} !^/bin
        RewriteCond %{REQUEST_URI} !^/content
        RewriteCond %{REQUEST_URI} !^/etc
        RewriteCond %{REQUEST_URI} !^/libs
        RewriteCond %{REQUEST_URI} !^/saml_login
        RewriteCond %{REQUEST_URI} !^/system
        RewriteCond %{REQUEST_URI} !^/tmp
        RewriteCond %{REQUEST_URI} !^/var
        RewriteCond %{REQUEST_URI} (.html|.jpe?g|.png|.svg)$
        RewriteRule ^/(.*)$ /content/brandA/us/en/$1 [NC,PT,L]
