### no-xhr-if.js [↪](https://github.com/gorhill/uBlock/blob/745fbd1c02b7179052ba97f51c54f7cb000636f0/assets/resources/scriptlets.js#L1171)
New in [1.38.0](https://github.com/gorhill/uBlock/commit/745fbd1c02b7179052ba97f51c54f7cb000636f0).
Defuses [XMLHttpRequest](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/Using_XMLHttpRequest) network requests by returning empty response. Based on [`no-fetch-if.js`](#no-fetch-ifjs-).
Parameters:
- optional, space-separated list of conditions which must be ALL fulfilled in order for the defusing to take place:
- string/_regular expression_ matching in URL passed to XMLHttpRequest `open()` call
- colon-separated `name:value` pairs of [XMLHttpRequest method `open()`](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/open#parameters) parameter names (only `method` and `url` currently supported) and string/_regular expression_ matching in value of passed argument.
When used without parameters, the parameters passed to `no-xhr-if` will be logged to the console, as `uBO: xhr.open(...list of arguments...)`.
Examples:
- `example.com##+js(no-xhr-if, method:HEAD)`
- `example.com##+js(no-xhr-if, adsbygoogle.js)`
- `example.com##+js(no-xhr-if, adsbygoogle.js method:HEAD)`
- `example.com##+js(no-xhr-if, /adsbygoogle.js$/ method:/HEAD|POST/)`
