this was caused by HTTP Cache-Control headers with syntax errors in their max-age stanza. Any stanza missing an = would cause the parser to skip the null instead of the = it assumed it had found The ign site had some js files with headers like $ curl -I https://apps.ign.com/video-player/release/6.4.4/default.d730d0c6.js HTTP/1.1 200 OK x-amz-id-2: QfISQVIgmXMngH++A8//RhnV9J40jB3h3TeT3IclQja93dt9WSgQAmHBUGJopnfEsIJdsxfPsq0= x-amz-request-id: 279AA2EE607F084B Last-Modified: Wed, 29 May 2019 23:43:41 GMT x-amz-version-id: cmxp2ovMdBYsW8ygV.SV5J_9X7sm9_2j ETag: "dbe1d57019f29b46b183d3a21b3297b2" Content-Type: application/javascript Server: AmazonS3 Access-Control-Allow-Origin: * Content-Length: 1259479 Accept-Ranges: bytes Date: Mon, 10 Jun 2019 19:56:04 GMT Via: 1.1 varnish Age: 0 Connection: keep-alive X-Served-By: cache-lcy19268-LCY X-Cache: MISS X-Cache-Hits: 0 X-Timer: S1560196564.082379,VS0,VE171 Vary: Accept-Encoding Cache-Control: max-age:30 bug fixed in http://source.netsurf-browser.org/netsurf.git/commit/?id=e598dcd139d8221f828d542ccf6f03466a5aecdc |
