Use "strpos" to validate "If-None-Match" header
Remove those "trim" calls and use "strpos" to check if the ETag value
generated by the system is contained somewhere in the "If-None-Match"
request header sent by the client (if present).
With this commit, the ETag header validation now also works with nginx.
The nginx web server prefixes the "ETag" header generated by the system
with the string "W/" which caused the previous validation code to fail.
Instead of using multiple "trim" calls or "preg_replace", we now use a
single, simple and fast "strpos" call to check if the system generated
Etag hash value is contained in the "If-None-Match" request header.
