Help: Parse ETag from a request and save it to a file
|
|
Protocols: HTTP
|
|
Added: 7.68.0
|

Category: http

|
|
This option saves an HTTP ETag to the specified file. Etag is
|
|
usually part of headers returned by a request. When server sends an
|
|
ETag, it must be enveloped by a double quote. This option extracts the
|
|
ETag without the double quotes and saves it into the <file>.
|
|
|
|
A server can send a weak ETag which is prefixed by "W/". This identifier
|
|
is not considered, and only relevant ETag between quotation marks is parsed.
|
|
|
|
It an ETag wasn't sent by the server or it cannot be parsed, an empty
|
|
file is created.
