    <p>I'm using nginx (v1.4.1) to proxy an external service, but would like to be able to inspect and possibly modify the body of a <code>POST</code> request before proxying it. The problem is, I'm currently unable to access the <code>POST</code> request body while handling the request, whether through the <code>$request_body</code> variable or otherwise.</p> <p>I've read a number of posts and SO questions, and have implemented <a href="https://stackoverflow.com/questions/4939382/logging-post-data-from-request-body">this suggested strategy</a>, which is intended to allow the logging of the <code>POST</code> body (when using a <code>proxy_pass</code> directive). However, while this works for me I'm still unable to read anything from <code>$request_body</code> during the processing of the request.</p> <p>For clarity, here's the relevant section of my configuration:</p> <pre><code>location /proxy-this/ { client_max_body_size 8k; client_body_buffer_size 16k; client_body_in_single_buffer on; proxy_pass https://example.com/external-endpoint/; proxy_set_header X-Real-IP $remote_addr; proxy_set_header Host $http_host; proxy_set_header Content-Length ''; } </code></pre> <p>And what I'd like to be able to do:</p> <pre><code>location /proxy-this/ { ... (same configuration as above) ... set $request_body $request_body&amp;extra_param=1; } </code></pre> <p>I'm aware that this is possible using the <code>nginx_lua</code> module, and have looked at the <code>HttpFormInputModule</code>, but the first seems overkill and the latter hasn't been updated in a while.</p>

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.
