Hypertext Cache Configuration

Purpose

Hypertext Cache Configuration controls whether fetched documents are stored for later reuse.

Use it to balance speed, disk use, freshness, and privacy.

What You Can Do Here

• Hypertext Cache Configuration controls whether fetched documents are stored for later reuse.
• Read the current value before changing it.
• Verify the effect on the public page, status page, or related administration page.

Page Architecture

Configuration pages usually contain persistent settings. A visible form writes values into YaCy configuration, while the backend may reload subsystems such as language files, network listeners, cache handling, or search presentation.

Control	Meaning	Values or examples
HTCachePath	The path where the cache is stored.	Text value; use the page label and surrounding context to choose the exact content.
maxCacheSize	The maximum size of the cache.	Integer value.
compressionLevel	Compression level.	Text value; use the page label and surrounding context to choose the exact content.
lockTimeout	Concurrent access timeout.	Text value; use the page label and surrounding context to choose the exact content.
set	Submits and applies the basic configuration.	Set
deleteCache	The path where the cache is stored.	The path where the cache is stored
deleteRobots	The path where the cache is stored.	The path where the cache is stored
deletecomplete	The path where the cache is stored.	Delete

Correct Use

Read the current value before changing it. Configuration changes often persist beyond the current request and may affect later crawling, search, network contact, authentication, or resource use. Change one operational idea at a time and verify the result.

Access And Safety

Administrator access is required. YaCy protects _p pages as administration pages.

Protected related endpoint(s): /ConfigHTCache_p.html.

Automation And API

Page backend: source/net/yacy/htroot/ConfigHTCache_p.java.

Endpoint	Method	Access	Backend
/ConfigHTCache_p.html	POST	admin	source/net/yacy/htroot/ConfigHTCache_p.java

Parameter Guide

The table explains values that an agent or script must set deliberately. Parameters not relevant to a task should be omitted or left at the page default.

Parameter	Meaning and valid values	Care
HTCachePath	The path where the cache is stored.	Set only when this option is part of the intended request; otherwise omit it and let YaCy use the page default.
maxCacheSize	The maximum size of the cache.	Set only when this option is part of the intended request; otherwise omit it and let YaCy use the page default.
compressionLevel	Compression level.	Set only when this option is part of the intended request; otherwise omit it and let YaCy use the page default.
lockTimeout	Concurrent access timeout.	Set only when this option is part of the intended request; otherwise omit it and let YaCy use the page default.
set	Submit action that saves the page settings.	Changes stored data, configuration, or a running job. Use the authenticated action flow where required and verify the result.
deleteCache	The path where the cache is stored.	Can remove data, stop work, expose access, or make a broad operational change. Use only with explicit confirmation and an exact target.
deleteRobots	The path where the cache is stored.	Can remove data, stop work, expose access, or make a broad operational change. Use only with explicit confirmation and an exact target.
deletecomplete	The path where the cache is stored.	Can remove data, stop work, expose access, or make a broad operational change. Use only with explicit confirmation and an exact target.

Example request shape:

POST /ConfigHTCache_p.html
Content-Type: application/x-www-form-urlencoded

HTCachePath=...&maxCacheSize=...&compressionLevel=...&lockTimeout=...&set=...

What To Expect

A successful change is visible as a saved value, a confirmation, or changed behavior on a related page. Some settings take effect immediately; others require reconnecting, reloading translations, restarting services, or watching the status page.
