# Class HTTPClient - [TopLevel.Object](/docs/commerce/b2c-commerce/references/b2c-script-api/TopLevel.Object.md) - [dw.net.HTTPClient](/docs/commerce/b2c-commerce/references/b2c-script-api/dw.net.HTTPClient.md) The HTTPClient class supports the HTTP methods GET, POST, HEAD, PUT, PATCH, OPTIONS, and DELETE. If a secure connection via HTTPS is established the used server certificate or the signing CAs certificate needs to be imported into the customer key store via Business Manager. **Note:** when this class is used with sensitive data, be careful in persisting sensitive information. Key selection for mutual TLS: 1. Check if there is an explicit identity requested [setIdentity(KeyRef)](/docs/commerce/b2c-commerce/references/b2c-script-api/dw.net.HTTPClient.md#setidentitykeyref) 2. Else, Check if there is a mapping for hostname in the keystore 3. Deprecated: Select an arbitrary private key from the keystore ``` var httpClient = new HTTPClient(); var message; httpClient.open('GET', 'http://www.myinstance.com/feed.xml'); httpClient.setTimeout(3000); httpClient.send(); if (httpClient.statusCode == 200) { message = httpClient.text; } else { // error handling message = "An error occurred with status code "+httpClient.statusCode; } ``` ## Constant Summary | Constant | Description | |

It basically means that a response is cached, and before making a request the HTTP client looks into the cache to determine whether the response is already available. Only responses with a status code of 2xx, with a content length, with a size less than 50k, and which are not intended to be immediately written to a file are cached. The provided parameter defines the TTL (time to live) for the cached content. A value of 0 disables caching. The URL and the username are used as cache keys. The total size of the cacheable content and the number of cached items is limited and automatically managed by the system. Cache control information send by the remote server is ignored. Caching HTTP responses should be done very carefully. It is important to ensure that the response really depends only on the URL and doesn't contain any remote state information or time information which is independent of the URL. It is also important to verify that the application sends exactly the same URL multiple times. **Parameters:** - ttl - the TTL for the cached content in secs *** ### getAllResponseHeaders() - ~~getAllResponseHeaders(): [HashMap](/docs/commerce/b2c-commerce/references/b2c-script-api/dw.util.HashMap.md)~~ - : Returns all response headers as a map containing the name and value of the response header. **Returns:** - a map containing the names and corresponding values of the response headers. **Deprecated:** :::warning Use [getResponseHeaders()](/docs/commerce/b2c-commerce/references/b2c-script-api/dw.net.HTTPClient.md#getresponseheaders) instead. ::: *** ### getAllowRedirect() - getAllowRedirect(): [Boolean](/docs/commerce/b2c-commerce/references/b2c-script-api/TopLevel.Boolean.md) - : Determines whether redirect handling is enabled. **Returns:** - true if redirect handling is enabled, false otherwise. *** ### getBytes() - getBytes(): [Bytes](/docs/commerce/b2c-commerce/references/b2c-script-api/dw.util.Bytes.md) - : Returns the bytes in the message body for HTTP status codes between 200 and 299. **Returns:** - the returned message body as bytes. *** ### getErrorBytes() - getErrorBytes(): [Bytes](/docs/commerce/b2c-commerce/references/b2c-script-api/dw.util.Bytes.md) - : Returns the returned message body as bytes for HTTP status code greater or equal to 400.

If the given timeout is less than or equal to zero, the timeout is set to a maximum value of 2 or 15 minutes, depending on the context. This timeout value controls both the "connection timeout" (how long it takes to connect to the remote host) and the "socket timeout" (how long, after connecting, it will wait without any data being read). Therefore, in the worst case scenario, the total time of inactivity could be twice as long as the specified value. The maximum timeout is 15 minutes when the client is used in a job, and 2 minutes otherwise. The default timeout for a new client is the maximum timeout value. This method can be called at any time, and will affect the next connection made with this client. It is not possible to set the timeout for an open connection. You should always set a reasonable timeout (e.g., a few seconds). Allowing connections to run long can result in thread exhaustion. **Parameters:** - timeoutMillis - timeout, in milliseconds, up to a maximum of 2 or 15 minutes, depending on the context. ***
