    <p>I am trying to figure out how to use proxy and multithreading.</p> <p>This code works:</p> <pre><code>requester = urllib3.PoolManager(maxsize = 10, headers = self.headers) thread_pool = workerpool.WorkerPool() thread_pool.map(grab_wrapper, [item['link'] for item in products]) thread_pool.shutdown() thread_pool.wait() </code></pre> <p>Then in <code>grab_wrapper</code></p> <pre><code>requested_page = requester.request('GET', url, assert_same_host = False, headers = self.headers) </code></pre> <p>Headers consist of: Accept, Accept-Charset, Accept-Encoding, Accept-Language and User-Agent</p> <p>But this does not work in production, since it has to pass proxy, no authorization is required. </p> <p>I tried different things (passing <code>proxies</code> to request, in headers, etc.). The only thing that works is this:</p> <pre><code>requester = urllib3.proxy_from_url(self._PROXY_URL, maxsize = 7, headers = self.headers) thread_pool = workerpool.WorkerPool(size = 10) thread_pool.map(grab_wrapper, [item['link'] for item in products]) thread_pool.shutdown() thread_pool.wait() </code></pre> <p>Now, when I run the program, it will make 10 requests (10 threads) and then... stop. No error, no warning whatsoever. This is the only way I can bypass proxy, but it seems like its not possible to use <code>proxy_from_url</code> and <code>WorkerPool</code> together.</p> <p>Any ideas how to combine those two into a working code? I would rather avoid rewriting it into scrappy, etc. due to time limitation</p> <p>Regards</p>

    1. COHave you tried to create a (proxy) requester per thread (each requester makes requests only from one thread)? Disclaimer: I don't use `urllib3` directly.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
