Filtering

Control which traffic APXY captures using filter rules.

Web UI

Open Filters from the Modify group. The page provides:

• Block rules form — add host patterns to exclude from capture
• Allow rules form — add host patterns to capture exclusively
• A list of active filter rules with delete buttons
• Access to recording controls so you can pause or resume capture while tuning rules

The Traffic page also has a built-in filter panel with:

• Protocol tabs (All/HTTP/HTTPS/WebSocket/JSON)
• Manual pinning of filters
• Saved filter presets

CLI

Block rules

Exclude noisy domains from capture:

# Block analytics and CDN traffic
apxy traffic filter set --type block --target "analytics.google.com"
apxy traffic filter set --type block --target "*.googleapis.com"
apxy traffic filter set --type block --target "cdn.example.com"

Blocked traffic is still forwarded to the server — it’s just not recorded by APXY.

Allow rules

When allow rules are set, only matching hosts are captured — everything else is ignored:

# Only capture traffic to your API
apxy traffic filter set --type allow --target "api.myapp.com"

Managing filters

# List active filters
apxy traffic filter list
 
# Remove a filter
apxy traffic filter remove --id <rule-id>

Recording control

Pause and resume traffic recording without stopping the proxy:

# Pause recording (proxy continues forwarding)
apxy recording stop
 
# Resume recording
apxy recording start
 
# Check recording status
apxy recording status

This is useful during noisy operations — pause before loading a page with many assets, then resume before the specific API call you want to capture.

Clearing traffic

# Delete all captured traffic
apxy logs clear
