WEBVTT 00:00:00.000 --> 00:00:04.672 This beginner walkthrough explains what an H-T-T-P status checker observes, when to 00:00:04.672 --> 00:00:09.344 use it, how to import or paste a list, how to run 00:00:09.344 --> 00:00:14.016 a complete fictional check, how final statuses differ from redirect chains, how 00:00:14.016 --> 00:00:18.688 to filter failures and compare snapshots, and what a successful response still 00:00:18.688 --> 00:00:19.467 cannot prove. 00:00:19.467 --> 00:00:24.352 This tool checks up to five hundred public U-R-Ls and records the 00:00:24.352 --> 00:00:29.238 final H-T-T-P status, final destination, each observed redirect hop, total latency, and 00:00:29.238 --> 00:00:34.124 selected response evidence. It also flags common redirect problems. Use that evidence 00:00:34.124 --> 00:00:39.010 for migration checks and audits, but remember that it describes the response 00:00:39.010 --> 00:00:42.267 path, not the complete quality of the page. 00:00:42.267 --> 00:00:48.071 Use the checker to validate migration or launch lists, prioritize four-x-x, five-x-x, 00:00:48.071 --> 00:00:53.875 and connection failures, simplify redirect chains, compare bounded crawler or language responses, 00:00:53.875 --> 00:00:59.679 compare status snapshots over time, or create an evidence-led remediation handoff. Each 00:00:59.679 --> 00:01:05.483 use case keeps the exact U-R-L and observed response attached to the 00:01:05.483 --> 00:01:05.967 decision. 00:01:05.967 --> 00:01:10.221 Paste one public U-R-L per line, choose Try an example, or import 00:01:10.221 --> 00:01:14.476 a leaf sitemap. A bare domain is treated as H-T-T-P-S, duplicate lines 00:01:14.476 --> 00:01:18.730 are removed, and the run is capped at five hundred. The disclosure 00:01:18.730 --> 00:01:22.985 says checks run on the server, results are not kept, and ordinary 00:01:22.985 --> 00:01:25.467 repeats may use a short-lived ten-minute cache. 00:01:25.467 --> 00:01:29.934 Choose Import sitemap, enter a public leaf sitemap U-R-L, and fetch its 00:01:29.934 --> 00:01:34.402 page locations. The fictional sitemap adds six reserved dot-example addresses and updates 00:01:34.402 --> 00:01:38.870 the count to one batch. A sitemap index is rejected here; select 00:01:38.870 --> 00:01:43.338 one child sitemap at a time. Imported U-R-Ls are still only inputs 00:01:43.338 --> 00:01:47.433 and are not proof that search engines crawl or index them. 00:01:47.433 --> 00:01:52.804 Advanced mode accepts only response-negotiation headers such as Accept-Language, Accept, Cache-Control, and 00:01:52.804 --> 00:01:58.174 Pragma. Credentials, cookies, and X-prefixed headers are refused, and headered checks bypass 00:01:58.174 --> 00:02:03.544 the cache. You can also choose browser, search-bot, or A-I crawler user-agent 00:02:03.544 --> 00:02:08.915 strings. That changes the request label; it does not make the request 00:02:08.915 --> 00:02:11.600 originate from a verified crawler network. 00:02:11.600 --> 00:02:16.719 The sample report shows two final two-hundred responses, one clean three-oh-one redirect, 00:02:16.719 --> 00:02:21.837 and one broken four-oh-four. The status pill, input U-R-L, final destination, latency, 00:02:21.837 --> 00:02:26.956 chain dots, flags, and expand control all have different jobs. Sort or 00:02:26.956 --> 00:02:32.074 filter a large list to prioritize work, then expand any redirect or 00:02:32.074 --> 00:02:34.633 error before deciding what to change. 00:02:34.633 --> 00:02:39.582 The soft-four-oh-four example is essential. A retired product can return H-T-T-P two 00:02:39.582 --> 00:02:44.531 hundred while showing Product unavailable or a repeated empty template. This checker 00:02:44.531 --> 00:02:49.480 correctly reports the response as successful; it cannot prove that the content 00:02:49.480 --> 00:02:54.429 is useful or indexable. Inspect rendered content with a crawler and confirm 00:02:54.429 --> 00:02:55.667 search classification separately. 00:02:55.667 --> 00:03:00.144 The full workflow is: paste or import up to five hundred U-R-Ls, 00:03:00.144 --> 00:03:04.621 select a user-agent only when needed, optionally add safe headers, run the 00:03:04.621 --> 00:03:09.098 check, filter or sort the streamed results, expand redirect rows, and export 00:03:09.098 --> 00:03:13.575 C-S-V or a local snapshot. The snapshot can be compared with a 00:03:13.575 --> 00:03:16.933 later run to call out status and chain changes. 00:03:16.933 --> 00:03:21.770 The complete example contains six reserved dot-example U-R-Ls: a multi-hop redirect, a 00:03:21.770 --> 00:03:26.607 live product, a retired product that still returns two hundred, a dead 00:03:26.607 --> 00:03:31.444 link, a temporary server failure, and a host that cannot be resolved. 00:03:31.444 --> 00:03:36.281 Every endpoint response is fulfilled locally and every external response is blocked, 00:03:36.281 --> 00:03:38.700 so no public site is contacted. 00:03:38.700 --> 00:03:43.491 Choose Check status codes. The table appears while batches run, then the 00:03:43.491 --> 00:03:48.283 summary confirms six U-R-Ls checked with the browser profile. A live run 00:03:48.283 --> 00:03:53.074 may vary with the server, network path, cache, bot protection, or deployment 00:03:53.074 --> 00:03:57.467 state. The fixed local response makes the evidence identical across retakes. 00:03:57.467 --> 00:04:02.565 The chips count six evaluated rows: three ending in two-x-x, one four-x-x, 00:04:02.565 --> 00:04:07.662 one five-x-x, and one connection error. Three-x-x is zero because the redirecting 00:04:07.662 --> 00:04:12.760 old-product U-R-L ultimately lands on two hundred. The pill shows the final 00:04:12.760 --> 00:04:17.433 response; the colored dots and flags reveal that redirects happened earlier. 00:04:17.433 --> 00:04:22.329 Expand old-product to see H-T-T-P three-oh-one to an intermediate catalog U-R-L, then 00:04:22.329 --> 00:04:27.225 a temporary three-oh-two, then the final two-hundred trail-shoe page. The tool flags 00:04:27.225 --> 00:04:32.121 a two-hop chain and the temporary redirect. Replace that path with one 00:04:32.121 --> 00:04:37.017 intentional permanent redirect to the correct final destination when the migration requirements 00:04:37.017 --> 00:04:37.833 support it. 00:04:37.833 --> 00:04:42.953 Live-product and retired-product both end on two hundred. The table can preserve 00:04:42.953 --> 00:04:48.073 a bounded title in expanded evidence, but a green pill still cannot 00:04:48.073 --> 00:04:53.193 validate the rendered copy, canonical choice, indexing directives, template quality, or search-engine 00:04:53.193 --> 00:04:58.313 soft-four-oh-four classification. Treat it as a successful server response and continue the 00:04:58.313 --> 00:04:59.167 content review. 00:04:59.167 --> 00:05:03.913 Choose the four-x-x chip to isolate the dead-link row. Four-oh-four means the 00:05:03.913 --> 00:05:08.660 requested page is missing; fix or remove internal links, or restore the 00:05:08.660 --> 00:05:13.407 intended resource. Five-oh-three is a server-side failure that may be temporary and 00:05:13.407 --> 00:05:18.153 should be retested. A D-N-S, T-L-S, timeout, or refused connection produces an 00:05:18.153 --> 00:05:22.900 error row, but this snapshot alone cannot identify the complete root cause. 00:05:22.900 --> 00:05:27.684 Use the row control to open the exact chain, select four-x-x to 00:05:27.684 --> 00:05:32.469 isolate broken pages, then return to All. The other chips isolate terminal 00:05:32.469 --> 00:05:37.253 three-x-x, server errors, or requests with no usable response. Sorting by status, 00:05:37.253 --> 00:05:42.037 latency, or chain length changes the view only; it does not change 00:05:42.037 --> 00:05:43.233 the captured evidence. 00:05:43.233 --> 00:05:48.214 Import a previously exported local snapshot to compare the same U-R-Ls. This 00:05:48.214 --> 00:05:53.196 baseline reports four changed rows, one new four-x-x, and one chain that 00:05:53.196 --> 00:05:58.177 grew. It also names the final-destination and error-state changes. A comparison is 00:05:58.177 --> 00:06:03.158 a triage aid: confirm the baseline date, deployment context, and each current 00:06:03.158 --> 00:06:05.233 row before assigning a regression. 00:06:05.233 --> 00:06:10.775 Export C-S-V for the input, final status, final U-R-L, redirect count, chain, 00:06:10.775 --> 00:06:16.317 latency, flags, and errors. Export evidence package adds structured per-U-R-L acquisition evidence 00:06:16.317 --> 00:06:21.859 and a decisive result image. Export snapshot creates the local baseline used 00:06:21.859 --> 00:06:27.401 by Compare snapshot. Review every not-evaluated row separately; an absent observation must 00:06:27.401 --> 00:06:30.633 never be converted into a clean result. 00:06:30.633 --> 00:06:35.501 Two-x-x means the chain ended with a successful H-T-T-P response, not that 00:06:35.501 --> 00:06:40.369 the content is healthy. A terminal three-x-x means the checker ended on 00:06:40.369 --> 00:06:45.237 a redirect response it could not or should not follow. Four-x-x identifies 00:06:45.237 --> 00:06:50.105 client-side missing or forbidden resources, five-x-x identifies server failure, and E-R-R means 00:06:50.105 --> 00:06:52.133 no usable H-T-T-P response completed. 00:06:52.133 --> 00:06:56.423 The browser divides the list into batches of up to twenty-five, keeping 00:06:56.423 --> 00:07:00.712 one host to ten or fewer U-R-Ls per batch, and dispatches batches 00:07:00.712 --> 00:07:05.001 at a deliberate pace. The server requests each U-R-L without automatic redirect 00:07:05.001 --> 00:07:09.290 following, records status and Location at every hop up to five, and 00:07:09.290 --> 00:07:13.579 reads the final H-T-M-L for one layer of meta refresh. Filtering, sorting, 00:07:13.579 --> 00:07:15.367 and exports then run locally. 00:07:15.367 --> 00:07:22.044 The main features are five-hundred-U-R-L runs, paced batches with progress, full expandable 00:07:22.044 --> 00:07:28.721 redirect chains, status filters and sortable columns, redirect-problem flags, leaf-sitemap import, several 00:07:28.721 --> 00:07:35.397 user-agent profiles, bounded request-header overrides, C-S-V and evidence exports, and local snapshots 00:07:35.397 --> 00:07:37.067 for later comparison. 00:07:37.067 --> 00:07:41.830 Checks come from datacenter edge I-Ps, so bot protection may answer differently 00:07:41.830 --> 00:07:46.594 than a real browser. A Googlebot label is not a verified Googlebot 00:07:46.594 --> 00:07:51.358 network. The tool follows H-T-T-P plus one meta refresh layer, not JavaScript 00:07:51.358 --> 00:07:56.121 navigation, and stops after five hops. It refuses private or gated targets, 00:07:56.121 --> 00:08:00.885 cannot prove content quality or indexability, and cannot turn one latency or 00:08:00.885 --> 00:08:03.267 connection error into a complete diagnosis. 00:08:03.267 --> 00:08:09.414 Export the exact U-R-Ls, final statuses, destinations, redirect chains, latency observations, flags, 00:08:09.414 --> 00:08:15.561 and errors with your handoff. Fix broken links and redirect rules at 00:08:15.561 --> 00:08:21.709 the source, then rerun the same list. Use a crawler, rendered-page inspection, 00:08:21.709 --> 00:08:27.856 Search Console, logs, and monitoring to validate content, indexability, JavaScript behavior, and 00:08:27.856 --> 00:08:32.467 availability questions that an H-T-T-P response alone cannot answer.
