# cURL Request Parameters

Below is a list of parameters followed by examples of request types:

&#x20;

<table><thead><tr><th width="199">Parameter</th><th>Description</th></tr></thead><tbody><tr><td>USERNAME</td><td>Username of proxy user.</td></tr><tr><td>dc</td><td>Indicates query for datacenter proxy.</td></tr><tr><td>country</td><td>Country code in two-letter format, not case sensitive. For example, nl indicates a proxy in the Netherlands; za for South Africa; it for Italy.</td></tr><tr><td>SID</td><td>Session ID keeps the same IP for next queries. Otherwise, a new IP is assigned for each new request. The same IP address is used until the end user device disconnects. Note that session time is determined by IP availability at the time of the request – if an IP from the pool is in use by another customer, it will not be available. SID supports any number up to 9 digits. The lowest SID can be sid-10000, and the highest SID can be sid-999999999.</td></tr><tr><td>PASSWORD</td><td>Proxy user password.</td></tr><tr><td>site URL</td><td>User’s destination site.</td></tr></tbody></table>

&#x20;

A basic query inserting only USERNAME and PASSWORD will be performed from a random IP address:

<mark style="color:blue;">`curl`</mark>`-x USERNAME-dc-any:PASSWORD@gw.netnut.net:5959 “example.site.com”`

You can request a specific country, as in the examples below:

<mark style="color:blue;">`curl`</mark>`-x  USERNAME-dc-nl:PASSWORD@gw.netnut.net:5959 “example.site.com”`

Add the **SID** (session ID) parameter to use the same IP for next queries. Note that SID must be preceded by a country:

<mark style="color:blue;">`curl`</mark>`-x USERNAME-dc-any-sid-947045456:PASSWORD@gw.netnut.net:5959” “example.site.com”`
