We should not set cache-control headers on RPC responses. HTTP caching
interacts poorly with resources that are expected to change frequently, or
whose rate of change is unpredictable.
More subtly, all calls to the POST endpoint use the same URL, which means a
cacheable response from one call may actually "hide" an uncacheable response
from a subsequent one. This is less of a problem for the GET endpoints, but
that means the behaviour of RPCs varies depending on which HTTP method your
client happens to use. Websocket requests were already marked statically
uncacheable, adding yet a third combination.
To address this:
- Stop setting cache-control headers.
- Update the tests that were checking for those headers.
- Remove the flags to request cache-control.
Apart from affecting the HTTP response headers, this change does not modify the
behaviour of any of the RPC methods.

<summary>Release notes</summary>
<p><em>Sourced from <a href="https://github.com/BurntSushi/toml/releases">github.com/BurntSushi/toml's releases</a>.</em></p>
<blockquote>
<h2>v1.0.0</h2>
<p>This release adds much more detailed errors, support for the <code>toml.Marshaler</code> interface, and several fixes.</p>
<p>There is no special meaning in the jump to v1.0; the 0.x releases were always treated as if they're 1.x with regards to compatibility; the versioning scheme for this library predates the release of modules.</p>
<h2>New features</h2>
<ul>
<li>
<p>Error reporting is much improved; the reported position of errors should now always be correct and the library can print more detailed errors (<a href="https://github-redirect.dependabot.com/BurntSushi/toml/issues/299">#299</a>, <a href="https://github-redirect.dependabot.com/BurntSushi/toml/issues/332">#332</a>)</p>
<p>Decode always return a <code>toml.ParseError</code>, which has three methods:</p>
<ul>
<li>
<p><code>Error()</code> behaves as before and shows a single concise line with the error.</p>
</li>
<li>
<p><code>ErrorWithLocation()</code> shows the same error, but also shows the line the error occurred at, similar to e.g. clang or the Rust compiler.</p>
</li>
<li>
<p><code>ErrorWithUsage()</code> is the same as <code>ErrorWithPosition()</code>, but may also show a longer usage guidance message. This isn't always present (in which case it behaves identical to <code>ErrorWithPosition()</code>), but it should be present for most common mistakes and sources of confusion.</p>
</li>
</ul>
<p>Which error the correct one to use is depends on your application and preferences; in general I would recommend using at least <code>ErrorWithPosition()</code> for user-facing errors, as it's much more helpful for users of any skill level. If your users are likely to be non-technical then <code>ErrorWithUsage()</code> is probably a good idea; I did my best to avoid technical jargon such as "newline" and phrase things in a way that's understandable by most people not intimately familiar with these sort of things.</p>
<p>Additionally, the TOML key that fialed should now always be reported in all errors.</p>
</li>
<li>
<p>Add <code>toml.Marshaler</code> interface. This can be used if you want full control over how something is marshalled as TOML, similar to <code>json.Marshaler</code> etc. This takes precedence over <code>encoding.TextMarshaler</code>. (<a href="https://github-redirect.dependabot.com/BurntSushi/toml/issues/327">#327</a>)</p>
</li>
<li>
<p>Allow TOML integers to be decoded to a Go float (<a href="https://github-redirect.dependabot.com/BurntSushi/toml/issues/325">#325</a>)</p>
<p>Previously <code>int = 42</code> could only be decoded to an <code>int*</code> type; now this can also be decoded in a <code>float</code> type as long as it can be represented without loss of data.</p>
</li>
</ul>
<h2>Fixes</h2>
<ul>
<li>
<p>Key.String() is now quoted when needed (<a href="https://github-redirect.dependabot.com/BurntSushi/toml/issues/333">#333</a>)</p>
</li>
<li>
<p>Fix decoding of nested structs on 32bit platforms (<a href="https://github-redirect.dependabot.com/BurntSushi/toml/issues/314">#314</a>)</p>
</li>
<li>
<p>Empty slices are now always <code>[]T{}</code> rather than nil, which was the behaviour in v0.3.1 and before. While they are identical for most purposes, encoding/json encodes them different (<code>[]</code> vs. <code>null</code>), making it an (accidentally) incompatible change (<a href="https://github-redirect.dependabot.com/BurntSushi/toml/issues/339">#339</a>)</p>
</li>
</ul>

* Rename rpctypes.Context to CallInfo.
Add methods to attach and recover this value from a context.Context.
* Rework RPC method handlers to accept "real" contexts.
- Replace *rpctypes.Context arguments with context.Context.
- Update usage of RPC context fields to use CallInfo.
No functional changes.
- Pull out a some helper code to simplify the control flow within the body of
the HTTP request handler.
- Front-load the URL path check so it does not get repeated for each request.
Instead of using anonymous maps, define tagged struct types for JSON argument
encoding. This allows us to have the encoding rules we want without tmjson.
This commit handles the "easy" cases. BroadcastEvidence is omitted here,
because it depends on the interface encoding rules from tmjson. I will address
that in a forthcoming change.
Defines a different concrete type that satisfies the service interface for a seed node.
update the seed node unit test to assert the new type.
Fixes#6775
* Update Caller interface and its documentation.
* Rework MapToRequest as ParamsToRequest.
The old interface returned the result as well as populating it. Nothing was
using this, so drop the duplicated value from the return signature. Clarify the
documentation on the Caller type.
Rework the MapToRequest helper to take an arbitrary value instead of only a
map. This is groundwork for getting rid of the custom marshaling code. For now,
however, the implementation preserves the existing behaviour for the map, until
we can replace those.
These two interfaces are identical, and besides HTTPClient being confusingly
named, all but one location uses Caller. Update that one location, and drop the
redundant interface.
Apart from the tests for the websocket client, positional parameters are not
used by RPC clients. The server supports both arrays and objects, but the
client only needs to provide one or the other.
Where possible, replace uses of the custom JSON library with the standard
library. The custom library treats interface and unnamed lteral types
differently, so this change avoids those even where it would probably be safe
to switch them.
These tests use a deterministic and unseeded random source to generate
non-colliding filenames for testing. When testing locally, this means tests are
not hermetic from one run to the next.
Use proper temp directories, and clean up after they're done.
* doc: fix typos in /tx_search and /tx.
* docs: update of go snippets for subscribe and unsubscribe operations
