Fix: Wrong URL variable used for extraction of raw html

[rbushri]

Summary

Fixes #1116 , #1178- Fixed incorrect URL variable used for extraction when processing raw HTML content. The extraction strategy was receiving the full HTML content as the URL parameter instead of the properly formatted URL identifier.

List of files changed and why

rawl4ai/async_webcrawler.py - Fixed line 610 to use _url instead of url in the extraction strategy call. The _url variable correctly handles raw HTML cases by displaying "Raw HTML" instead of passing the entire HTML content as the URL parameter.

How Has This Been Tested?

Local Testing:

• Tested the fix locally by running crawl4ai with raw HTML content using the raw: prefix
• Verified that the extraction strategy now receives "Raw HTML" as the URL parameter instead of the full HTML content
• Confirmed that the content sent to LLM extraction strategies is significantly reduced (no longer includes the full HTML as URL parameter)
• Tested that normal URL crawling (non-raw HTML) continues to work as expected with the actual URL being passed to extraction strategies

Walkthrough

The extraction call in crawl4ai/async_webcrawler.py’s aprocess_html now passes _url instead of url to extraction_strategy.run, ensuring raw HTML inputs use a placeholder ("Raw HTML") while normal URL flows remain unchanged. No other logic, signatures, or control flow were modified.

Changes

Cohort / File(s)	Summary
Extraction URL context fix crawl4ai/async_webcrawler.py	In aprocess_html, changed extraction_strategy.run argument from url to _url to pass correct URL context for raw HTML; no other logic altered.

Poem

I nibbled on bytes, a curious spree,
Swapped a tiny var—now lighter the sea!
No more HTML stuffed in the URL stew,
The extractor hums, lean, swift, and true.
Thump-thump goes my paw—ship it, whee! 🐇✨

618-618: Fix is correct: pass _url to extraction strategy for raw HTML.

This prevents leaking the full raw HTML via the url param into extraction strategies while preserving the normal URL path. Matches the PR objective.

This is a very important PR. It enables to send raw html for extraction. Please merge.
