I don't think this line is doing any good since it sets options after self.session is created. I'm pretty sure it's only the get line below that's doing any good.

This line is needed for my proxy setup. I use this line to modify the HTTP headers on the request session. If you look inside http_util.py, the set_session_options function adds the keywords I need. Specifically the "User-Agent" parameter in the header.

If that's the case, you really should call set_session_options() before calling create_session(). set_session_options only affects subsequent calls to create_session.

Interesting... if I comment out set_session_options after create_session() my code fails from the proxy blocking the request. I expect this.
If I move the set_session_options line before create_session() my code fails from the proxy blocking the request on Line 282 self.session.get(catalog_url, **kwargs). The same failure if comment out set_session_options. This is unexpected based on what you told me.
I'm not going to pretend like I understand what is going on. I just know the code in this PR is the only thing that works for my network.

Can you show the relevant sample of code you're using with siphon? At least the code that creates a TDSCatalog up to the point that fails? I feel like there's something I'm missing here... (You can add that in a stand-alone comment below since I think we're getting a little long-winded here)

Just added another comment with some relevant code samples. Sorry it took so long, ran into some issues with cftime package updating and manifesting another bug in pvlib.

I made another repo that shows how I am using this PR. I am doing solar forecasting with PVLIB which uses Siphon to gather data. I had to modify PVLIB to pass additional arguments into Siphon in order to successfully get the request through my corporate proxy. I hope you can follow my readme when creating the test environment.

Description Of Changes
My corporate network does not allow for standard SSL connections to weather forecast servers. I found that by allowing for passing keywords into the TDSCatalog object and then further into the session manager, I could send the appropriate headers and option flags into urllib that allow the get request to succeed.
