Compatibility with Spring Boot 3 / Spring Framework 6

[Yashwanth-G]

First, thank you for maintaining this library — it’s been a useful component in many Spring-based applications.

We’re currently migrating our application from Spring Boot 2.7.x to Spring Boot 3.x.x, which brings in Spring Framework 6. As part of this upgrade, we noticed that Smiley's HTTP Proxy Servlet depends on Apache HttpClient 4, which is not compatible with Spring Web 6, which now uses Apache HttpClient 5 by default.

Given that Spring Boot 3 introduces breaking changes and updated dependencies, could you please confirm:

• Are there any plans to update Smiley's HTTP Proxy Servlet to support Spring Boot 3 / Spring Framework 6?
• Is there a roadmap or timeline for this upgrade (if planned)?

Thanks in advance!

This servlet has no dependency on Spring stuff, but I get your point.
I have no plans; I'm a passive maintainer here.

That said, I think what's needed is a conversion to Java 11's HttpClient, thus be dependency-free aside from the Servlet spec. Perhaps an LLM could make this happen.

Hi, is since this project is just being passively maintained, would you suggest any other project instead, goiing forward? We really want to get rid of the old HttpClient 4, and this lovely little piece of software (the ProxyServlet), that has been so helpful, is now sadly and suddenly blocking progress.

This project's README, at the bottom, has a semi-dated link to Jetty's ProxyServlet. It uses Jetty's HttpClient. I recently tried to use it and found it to be impressive; I suspect it's higher performance with its asynchronous IO support. I did a POC of sorts for using it within Solr... partial success/failure but ultimately found that for Solr's embedded use, the async matters that the Jetty servlet insisted on using were not compatible with the non-asynchronous/classic Servlet that Solr used. So YMMV.

We live in amazing times: #257
I encourage your review... I'll look into it further this weekend.
