WEB TEXT & DOCUMENT SCRAPING

Collect public text and documentswith scale and geographic control

Use high-bandwidth proxy infrastructure for public pages and documents, then add geo-targeted residential proxies only where location changes the content.

01 / Workload

Text workloads combinediscovery, transfer, and parsing

Page count, document size, rendering, and regional differences determine the proxy strategy.

URL scheduling

Manage sites, sections, and update windows.

HTML and documents

Separate pages, PDFs, and public files.

Regional content

Use residential routing only when geography matters.

Parsing and deduplication

Extract content and remove repeated documents downstream.

02 / Scenarios

For distributed sourcesand mixed formats

High-bandwidth proxies provide scale while residential proxies provide explicit regional identity.

News and blog corpora

Discover, fetch, and extract public articles incrementally.

Focus: incremental

Forums and discussions

Preserve topics, pages, and reply structure.

Focus: relationships

PDFs and documents

Download files with source and version metadata.

Focus: completeness

03 / Architecture

Partition by source, then choose the proxy policy

HTML, browser-rendered pages, and PDFs have different capacity and validation models.

Define site boundaries

Record public sources and allowed collection scope.

Select proxy by queue

Use high bandwidth for scale and residential for geo.

Fetch and parse separately

Route HTML, browsers, and documents to different workers.

Deduplicate with provenance

Store content, source, time, and processing state.

04 / Proxy strategy

Use high bandwidth for scale and residential proxies for explicit geography

Public web and document transfer should start with high-bandwidth proxy IP. Add geo-targeted residential proxy only for location-dependent search or local content.

05 / Validation

Validate useful documents and field completeness

HTTP 200 does not prove useful text; include rendering, parsing, deduplication, and provenance.

Useful documents: Documents passing content and language rules
Fetch success: URLs returning usable pages or files
Parse success: Documents with required text and fields
Geo match: Regional exits matching the requested location
Duplicate rate: Documents removed by URL or content rules
Provenance: Documents retaining source, time, and version

Validate all capacity assumptions with representative public targets, real response sizes, retry behavior, and the required completion window.

06 / Developer access

Use proxy policies by queue in the same collection framework

Scrapy, requests, and Playwright can share a task system while using different proxy configurations by source and workload.

Python / public documentIntegration example

import requests

proxy = "http://user:pass@proxy.123proxy.cn:9000"
response = requests.get(
    "https://target.example/public-document",
    proxies={"http": proxy, "https": proxy},
    timeout=30,
)

07 / FAQ

Questions to answer before production

Validate workload boundaries, useful throughput, retry behavior, and dataset completeness with representative public targets.

Why not use residential proxies for every text request?

Large-scale page and document transfer is usually constrained first by bandwidth and total transfer cost.

What locations are supported?

Residential proxy coverage includes 190+ countries and regions, subject to current console availability.

What about JavaScript-rendered pages?

Use browser automation through standard proxies and measure worker CPU, memory, and page completion.

Should PDFs and HTML share one queue?

No. Their sizes, timeouts, and validation behavior differ.

Is content parsing included?

Not in the standard proxy scope. Parsing and quality remain in the customer pipeline.

How do we know geo targeting is required?

Run small regional comparisons and observe content, fields, results, or status differences.

How should crawl rate be controlled?

Configure site-level concurrency, delay, timeout, and retry while respecting applicable terms and boundaries.

What provenance should be stored?

Retain source URL, site, collection time, version, proxy policy, and processing status.

Validate the proxy mix with representative public sites

Share source types, geographic requirements, document scale, framework, and completion needs.
