Add --no-header option to remove specific HTTP header request

[jcamiel]

Add --no-header foo option to remove all HTTP headers foo from HTTP request.

Discussed in #4824

I have this hurl file that will make a request to an endpoint which will return a presigned url

I then use that presigned url to upload a file but the issue I'm having is I set the authorization header via the --header flag and I'd like to exclude that header from the request that is made to the presigned url

# ─── Get S3 presigned upload URL ──────────────────────────────────────────────
PUT {{base_url}}/upload
[Options]
location: false

HTTP 307
[Captures]
upload_url: header "Location"


# ─── Upload file to S3 ────────────────────────────────────────────────────────
PUT {{upload_url}}
Content-Type: image/png
[Options]
location: false
file,testdata/logo.png;

HTTP 200

Is there a way to make the second request not include the --header authorization?

Hi, I've been looking into this and traced the root cause.

Proposed approach: 1. Study how existing --header option is implemented across CLI parsing, Hurl file [Options] section, and HTTP client layer. 2. Add --no-header CLI option that accepts a header name. 3. Add no-header support in [Options] section of .hurl files for per-request control. 4. Implement header removal logic in the HTTP client before request dispatch. 5. Add integration tests following existing test patterns. Key files likely in packages/hurl/src/cli/, packages/hurl_core/src/parser/, and packages/hurl/src/http/. Note: commits must be GPG/SSH signed and verified by GitHub.

I'll open a draft PR shortly. Happy to adjust based on your preference.

May be we can use the httpie way https://httpie.io/docs/cli/empty-headers-and-header-un-setting :

• my-header: unset header (colon)
• my-header; set empty header (semicolon)
