HaRP passes an ExApp's redirect to the browser unchanged, but the PHP ExApp proxy let Nextcloud's HTTP client follow it on the server, up to five times, and returned the last response instead. The browser stayed on the first URL, and only that first path was matched against the ExApp's routes.

The proxy now returns a 3xx response with its Location as it is, as HaRP does, so the browser follows it and each target goes through the proxy and its route check again. Redirects no longer get the proxy's one-hour cache header; a 304 Not Modified keeps it.

On a Docker Socket Proxy or manual-install daemon, an ExApp that redirects to an absolute path such as /login now sends the browser to that path on the Nextcloud host, as it already does through HaRP. Relative redirects work the same through both.

Changes

• The four proxy actions no longer follow redirects.
• Redirect responses do not get the one-hour cache header.
• A test for each action and for a 304.

Walkthrough

The ExApp proxy disables automatic redirect following for GET, POST, PUT, and DELETE requests. It returns redirect responses to the browser and excludes statuses 301, 302, 303, 307, and 308 from the one-hour cache path. Tests check the returned status and Location header, and verify that a 304 response retains max-age caching. The changelog documents the redirect behavior.

Merge Risk: Moderate · up to 85bba

Returning ExApp redirects to the browser is an intended change, but ExApp responses that set several cookies alongside a redirect will lose all but the first. Successful redirect-based logins also stop clearing an earlier brute-force delay. Both should be addressed or explicitly accepted before merge.

Full details: Docstring Coverage

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 6 functions across 2 files. (1 skipped: 1 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Preserve all cookies on redirect responses.

If an ExApp returns two Set-Cookie headers with a redirect, this code forwards only the first. The browser follows the redirect without the second cookie, which can break session or CSRF-dependent flows. Preserve each Set-Cookie field separately. (rfc-editor.org)

@coderabbitai About keeping every Set-Cookie of a redirect: this existed before this PR. The proxy keeps only the first value of each header, on 2xx responses too, and before it a redirect's cookies did not reach the browser at all. It's handled separately.

Tip

For best results, initiate chat on the files or code changes.

@oleksandr-nc Thanks for the clarification. The header limitation predates this PR, and you’re handling it separately.

If there is no follow-up issue yet, would you like me to open one?
