# Настройка сервера через переменные окружения

* `WA_CORS_ORIGINS` — от каких источников принимать запросы. Значение по умолчанию отсутствует. **Если переменная не задана**, то CORS headers отключены**,** т.е. внутри контейнера Web SDK **никакие cors headers не будут добавлены!**
* `WA_CORS_METHODS`*(необязательно)* — Методы HTTP, которые могут использоваться. Если значение переменной не задано, она принимает значение по умолчанию: `'GET, POST, OPTIONS'`. Если переменная не указана, можно использовать все методы.
* `WA_CORS_HEADERS`*(необязательно)* — Заголовки HTTP, которые могут использоваться. Если значение переменной не задано, она принимает значение по умолчанию: `'DNT, X-CustomHeader, Keep-Alive, User-Agent, X-Requested-With, If-Modified-Since, Cache-Control, Content-Type, traceparent, tracestate, esid, shield-id, Correlation-ID'`. Если переменная не указана, можно использовать все заголовки.

Пример настройки CORS headers через переменные окружения:

```bash
docker run -d -p 80:80 \
-e WA_CORS_ORIGINS='*' \
-e WA_CORS_METHODS='GET, POST, OPTIONS' \
-e WA_CORS_HEADERS=DNT, X-CustomHeader, Keep-Alive, User-Agent, X-Requested-With, If-Modified-Since, Cache-Control, Content-Type, traceparent, tracestate, esid, shield-id, Correlation-ID \

# Agent Instructions

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://doc.ozforensics.com/oz-knowledge-ru/rukovodstva/rukovodstvo-administratora/web-adapter/nastroika-servera-cherez-peremennye-okruzheniya.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
