Wget "waiting for response"

[sofasurfer]

Trying to download electrical schematic from https://www.autozone.com/user/repairGuideContent/3506783649/0996b43f8025eecb
I use <$ wget https://www.autozone.com/user/repairGuideContent/3506783649/0996b43f8025eecb> and all I get is a never ending "waiting for response". Whats the secret?

Is the address correct? I don't see anything at that address

 

[sofasurfer]

Yes that address works for me. It brings up a page with multiple schematics. For a better test here is the exact image I want to download https://www.autozone.com/znetrgs/re...96b43f/80/24/52/16/large/0996b43f80245216.gif
I enclosed a screenshot of the image at that address.

use

wget -U 'Mozilla/5.0' https://www.autozone.com/znetrgs/repair_guide_content/en_us/images/0996b43f/80/24/52/16/large/0996b43f80245216.gif

It passes Mozilla/5.0 as a header to the page and for me allowed it to download.

I tried posting a solution but it is awaiting moderator approval so i'll just send this instead. This passes Mozilla/5.0 as a header to the page and for me allowed it to download.

 

[sofasurfer]

That did it, THANKS.
Now, if its not to much trouble, do you have an explaination for "This passes Mozilla/5.0 as a header to the page"? What does this do? If its to complex thats ok, I'll be looking it up.

You get that if you post a URL before you have a half a dozen Posts under your belt - spam protection. I have approved it now.

from what I understand, when you send an HTTP request/response you send information to the server such as operating system, type of connection, etc. and in this case the server requires to know what browser you are using in order to download the file. the -U "browser" tells it, in this case, that you are using Mozila/5.0. if you run

wget -S address

you can see the header information of the HTTP request/response.

The server was probably set up to reject, or ignore http requests with no user-agent, which is why you got the "waiting for a response" message.

By passing "Mozilla/5.0" via wget's -U (user-agent) option - it effectively tells the server that the request is coming from a mozilla browser. So you're spoofing the connection to make it look like it's a browser that's connecting. Then the server will accept the request and respond.

:Edit:
I should have read the entire thread before posting, looks like @xanifer already answered that question! Oops! :/ Ha ha!

Nice effort, though
