Handling GET /favicon.ico HTTP/1.1 Requests

Hi All,

 

The logs in AEM Dispatcher and HTTPD Access are flooded with GET /favicon.ico.

 

My favicon is present in clientlibs and rendering correctly as seen on the page's HTML -

<link rel="icon" type="image/png" href="/etc.clientlibs/brandA/clientlibs/clientlib-favicon/resources/favicon-brandA-180x180.png">
<link rel="icon" type="image/png" href="/etc.clientlibs/brandA/clientlibs/clientlib-favicon/resources/favicon-brandA-32x32.png" sizes="32x32">
<link rel="icon" type="image/png" href="/etc.clientlibs/brandA/clientlibs/clientlib-favicon/resources/favicon-brandA-192x192.png" sizes="192x192">

 

Query - How can I handle these requests which are currently going to 404 ?

 

Please find both the logs (Access and Request Logs) below -

    @rohan_garg Usually browser/search engines make favicon request under root domain, ie. /favicon.ico

     

    I suggest you add a redirect rule to handle this request

     

    RewriteRule ^/favicon.ico$/etc.clientlibs/brandA/clientlibs/clientlib-favicon/resources/favicon-brandA-32x32.png [PT,NC,L]

     

    * Just test if .ico will work with .png response.

      Hi Mohit, Thanks for the quick reply!

      I had added the below rule which did not work -

       

      #Rewrite Rule for Favicon
      RewriteRule "^/favicon.ico" "/etc.clientlibs/brandA/clientlibs/clientlib-favicon/resources/favicon-brandA-180x180.png" [PT,L]

       

      Any issue with the above redirect rule you think ?

        Avoid quote " in your syntax

        RewriteRule ^/favicon.ico$/etc.clientlibs/brandA/clientlibs/clientlib-favicon/resources/favicon-brandA-32x32.png [PT,NC,L]

          Hi @rohan_garg,

           

          Firstly, I assume that you might have already considered writing a rewrite rule, if not – see if this example helps as reference.

          RewriteCond %{REQUEST_URI} ^/favicon.ico$
RewriteRule ^/favicon.ico$ /content/dam/<folder-name>/favicon.ico [NC,PT]

          Secondly, even though you have a correct rewrite rule, make sure your "/etc.clientlibs/brandA/clientlibs/clientlib-favicon/resources/favicon*" (your favicon path) is not blocked, as we usually block the etc/* paths.

          Thirdly, I would suggest moving your client libs to apps and that is what even Adobe suggests and make use of allow proxy property to get access to your resources folder under client libs.

            Hi Sravan, Thank you for your response.

            Our clientlibs are already present in /apps/projectFolder/clientlibs with allowProxy set to true.

             

            The etc.clientlibs is not blocked but rather allowed in our filter rules.

            I will give the rewrite rule to /content/dam/brandsA/favicon.ico and place a dummy asset in DAM.

            Will let you know how it works out! Thanks!
