In my case, I found that the “pending” status was caused by the AdBlock extension. The image that I couldn’t get to load had the word “ad” in the URL, so AdBlock kept it from loading. Disabling AdBlock fixes this issue. Renaming the file so that it doesn’t contain “ad” in the URL also fixes … Read more
I managed to find network.http.connect.timeout for much older versions of Mozilla: This preference was one of several added to allow low-level tweaking of the HTTP networking code. After a portion of the same code was significantly rewritten in 2001, the preference ceased to have any effect (as noted in all.js as early as September 2001). … Read more
I must clarify that no-cache does not mean do not cache. In fact, it means “revalidate with server” before using any cached response you may have, on every request. must-revalidate, on the other hand, only needs to revalidate when the resource is considered stale. If the server says that the resource is still valid then … Read more
A Uniform Resource Identifier (URI) is a string of characters used to identify a name or a resource on the Internet. A URI identifies a resource either by location, or a name, or both. A URI has two specializations known as URL and URN. A Uniform Resource Locator (URL) is a subset of the Uniform … Read more
307 came about because user agents adopted as a de facto behaviour to take POST requests that receive a 302 response and send a GET request to the Location response header. That is the incorrect behaviour — only a 303 should cause a POST to turn into a GET. User agents should (but don’t) stick … Read more
Difference between PUT, POST, GET, DELETE and PATCH in HTTP Verbs: The most commonly used HTTP verbs POST, GET, PUT, DELETE are similar to CRUD (Create, Read, Update and Delete) operations in database. We specify these HTTP verbs in the capital case. So, the below is the comparison between them. Create – POST Read – … Read more
There is no limit in theory. For HTTP URLs, the HTTP 1.1 specification states: The HTTP protocol does not place any a priori limit on the length of a URI. Servers MUST be able to handle the URI of any resource they serve, and SHOULD be able to handle URIs of unbounded length if they … Read more
Neither of these headers are officially standardised. Therefore: What is the difference between HTTP_CLIENT_IP and HTTP_X_FORWARDED_FOR? – it is impossible to say. Different proxies may implement these, or may not. The implementations may vary from one proxy to the next, and they may not. A lack of a standard breeds question marks. Why would one … Read more
Assuming you want your client to work with other servers, and server to work with other clients, your server can’t expect to be treated nicely. There are two ways to tell when the body has ended. Neither of them require knowledge of the body’s content type as you suggest (e.g., don’t bother looking for </html> … Read more
You’re looking for the –data-binary argument: curl -i -X POST host:port/post-file \ -H “Content-Type: text/xml” \ –data-binary “@path/to/file” In the example above, -i prints out all the headers so that you can see what’s going on, and -X POST makes it explicit that this is a post. Both of these can be safely omitted without … Read more
