# Entry
## Definition
A Hurl file is a list of entries, each entry being a mandatory [request], optionally followed by a [response].
Responses are not mandatory, a Hurl file consisting only of requests is perfectly valid. To sum up, responses can be used
to [capture values] to perform subsequent requests, or [add asserts to HTTP responses].
## Example
```hurl
# First, test home title.
GET https://acmecorp.net
HTTP/1.1 200
[Asserts]
xpath "normalize-space(//head/title)" == "Hello world!"
# Get some news, response description is optional
GET https://acmecorp.net/news
# Do a POST request without csrf token and check
# that status code is Forbidden 403
POST https://acmecorp.net/contact
[FormParams]
default: false
email: john.doe@rookie.org
number: 33611223344
HTTP/1.1 403
```
## Description
### Options
[Options] specified on the command line apply to every entry in an Hurl file. For instance, with [`--location` option],
every entry of a given file will follow redirection:
```shell
$ hurl --location foo.hurl
```
You can use an [`[Options]` section] to use option only for a specified option. For instance, in this Hurl file:
```hurl
GET https://google.fr
HTTP/* 301
GET https://google.fr
[Options]
location: true
HTTP/* 200
GET https://google.fr
HTTP/* 301
```
The second entry will follow location (and so we can test the status code to be 200 instead of 301).
You can use it to logs a specific entry:
```hurl
# ... previous entries
GET https://api.example.org
[Options]
very-verbose: true
HTTP/* 200
# ... next entries
```
### Cookie storage
Requests in the same Hurl file share the cookie storage, enabling, for example, session based scenario.
### Redirects
By default, Hurl doesn't follow redirection. To effectively run a redirection, entries should describe each step
of the redirection, allowing insertion of asserts in each response.
```hurl
# First entry, test the redirection (status code and
# Location header)
GET https://google.fr
HTTP/1.1 301
Location: https://www.google.fr/
# Second entry, the 200 OK response
GET https://www.google.fr
HTTP/1.1 200
```
Alternatively, one can use [`--location`] option to force redirection
to be followed. In this case, asserts are executed on the last received response. Optionally, the number of
redirections can be limited with [`--max-redirs`].
```hurl
# Running hurl --location google.hurl
GET https://google.fr
HTTP/1.1 200
```
Finally, you can force redirection on a particular request with an [`[Options]` section][options] and the [`--location` option]:
```hurl
GET https://google.fr
[Options]
location: true
HTTP/1.1 200
```
### Retry
Every entry can be retried upon asserts, captures or runtime errors. Retries allow polling scenarios and effective runs
under flaky conditions. Asserts can be explicit (with an [`[Asserts]` section][asserts]), or implicit (like [headers] or [status code]).
Retries can be set globally for every request (see [`--retry`], [`--retry-interval`] and [`--retry-max-count`] options),
or activated on a particular request with an [`[Options]` section][options].
For example, in this Hurl file, first we create a new job, then we poll the new job until it's completed:
```hurl
# Create a new job
POST http://api.example.org/jobs
HTTP/* 201
[Captures]
job_id: jsonpath "$.id"
[Asserts]
jsonpath "$.state" == "RUNNING"
# Pull job status until it is completed
GET http://api.example.org/jobs/{{job_id}}
[Options]
retry: true
HTTP/* 200
[Asserts]
jsonpath "$.state" == "COMPLETED"
```
