Help: Pass an ETag from a file as a custom header
|
|
Protocols: HTTP
|
|
Added: 7.68.0
|
|
Category: http
|
|
Example: --etag-compare etag.txt $URL
|
|
See-also: etag-save time-cond

|
|
This option makes a conditional HTTP request for the specific ETag read
|
|
from the given file by sending a custom If-None-Match header using the
|
|
stored ETag.
|
|
|
|
For correct results, make sure that the specified file contains only a
|
|
single line with the desired ETag. An empty file is parsed as an empty
|
|
ETag.
|
|
|
|
Use the option --etag-save to first save the ETag from a response, and
|
|
then use this option to compare against the saved ETag in a subsequent
|
|
request.
