jkroon-immt opened a new issue #1080: CouchDB failing to replicate behind a proxy server URL: https://github.com/apache/couchdb/issues/1080 ## Expected Behavior When replicating from a remote CouchDB database to a CouchDB database on the local PC via a proxy, replication should be successful. ## Current Behavior CouchDB is seeing localhost / 127.0.0.1 as an HTTP-based target and assuming it needs to use the proxy, this causes replication to fail with CouchDB reporting an 'invalid_json' error due to the request via the proxy returning an error HTML page. ## Possible Solution A possible quick solution would be to add a check for localhost URLs and not use the proxy for those. Alternatively, it may be useful to add a sourceProxy and targetProxy, leaving the current proxy setting to behave as is. So the logic for getting the source poxy in the code would be to look at sourceProxy first, then the current proxy setting. Similarly for the target. The benefit of this alternate approach would be that you can proxy localhost if you need to (e.g. for local development using Fiddler). ## Steps to Reproduce (for bugs) This can be easily reproduced by using a replication document similar to the one provided below in the /_replicator/ database. ``` { "_id": "rep_init", "_rev": "20-81f3b1999b7f8e9ac51a45e3acbc4432", "source": "https://<username>:<password>@dbgateway.<domain>.com/<source_db_name>", "target": "http://127.0.0.1:5984/<target_db_name>", "create_target": false, "continuous": false, "filter": "replication_filter/no_ddocs", "owner": null, "proxy": "http://<proxy_ip_address>:<proxy_port>", "_replication_state": "error", "_replication_state_time": "2017-12-07T15:59:12+08:00", "_replication_state_reason": "{invalid_json,{error,{1,invalid_json}}}", "_replication_id": "d449aac07eeb8da0e322d4646e0b0f9a" } ``` ## Context [For further context please refer to the following](https://lists.apache.org/thread.html/c330159c25dc6311d9d58f5ee395d85d76bac499c28beb937bc4d4eb@%3Cuser.couchdb.apache.org%3E) ## Your Environment * Version used: 2.0.0 (also reproducible in CouchDb 2.1.1) * Operating System and version (Desktop): Windows 10
