From 9d10be33aebb08058c37d7dcd15874e42be74a29 Mon Sep 17 00:00:00 2001 From: Christopher Faulet Date: Tue, 8 Jul 2025 08:38:31 +0200 Subject: [PATCH] BUG/MINOR: http-client: Ignore 1XX interim responses in non-HTX mode When the response is re-formatted in raw message, the 1XX interim responses must be skipped. Otherwise, information of the first interim response will be saved (status line and headers) and those from the final response will be dropped. Note that for now, in HTX-mode, the interim messages are removed. This patch must be backported as far as 2.6. --- src/http_client.c | 17 +++++++++++++++++ 1 file changed, 17 insertions(+) diff --git a/src/http_client.c b/src/http_client.c index 809e437d5..a43022c90 100644 --- a/src/http_client.c +++ b/src/http_client.c @@ -648,6 +648,23 @@ void httpclient_applet_io_handler(struct appctx *appctx) if (!sl || (!(sl->flags & HTX_SL_F_IS_RESP))) goto out; + /* Skipp any 1XX interim responses */ + if (sl->info.res.status < 200 && + (sl->info.res.status == 100 || sl->info.res.status >= 102)) { + while (blk) { + enum htx_blk_type type = htx_get_blk_type(blk); + uint32_t sz = htx_get_blksz(blk); + + c_rew(res, sz); + blk = htx_remove_blk(htx, blk); + if (type == HTX_BLK_EOH) { + htx_to_buf(htx, &res->buf); + break; + } + } + break; + } + /* copy the status line in the httpclient */ hc->res.status = sl->info.res.status; hc->res.vsn = istdup(htx_sl_res_vsn(sl)); -- 2.47.2
